100 Meta Ads Interview Questions and Answers (2026)
100 Meta ads interview questions with answers from a D2C operator who hires for the role: Advantage+, Pixel and CAPI, creative testing, COD and a mock test.
Updated October 2026.
Meta ads interview questions test whether you can run Facebook and Instagram ads that make money, not just ads that get clicks. This page has 100 Meta ads (Facebook ads) interview questions with model answers, from fresher basics to scenarios for 2 to 5 years of experience, using the names Meta uses in 2026 and the numbers worked out in rupees.
I'm Raviraj Ramavarapu, founder of Compound Lab, a retention agency. I've hired performance marketers and performance marketing agencies, and I ran the ecommerce P&L at Healthify Store, which meant owning what Meta spend brought in. I've run Meta budgets of up to about ₹30 lakh. Today I handle Meta performance for a client, including the full creative output. The thing I listen for in every paid answer is simple. Does the candidate know what a customer is worth after the first order, or only what the click cost?
How this page works. The 100 questions are split into five sections of 20, from the basics to D2C scenarios for people with some experience. Tap your section below to jump straight to it, or scroll down to read everything in order. Want to test yourself first? The last box opens a 10-question mock interview, with your score at the end and no sign-up.
What interviewers look for in a Meta ads candidate
Knowing where the buttons are gets you through round one. After that, interviewers want three things. That you understand creative is now most of the targeting. That you judge campaigns on profit, not Meta's ROAS alone. And that your knowledge is current, because Meta renames and retires features every year, and most guides still describe the Ads Manager of 2020.
| Weak answer | Strong answer |
|---|---|
| "I'd target people interested in fitness" | "I'd go broad and let three creative angles find their own audiences" |
| "ROAS was 3x, so it worked" | "3x on Meta's attribution, against a break-even of 2.2x, and better once repeat orders came in" |
| "I'd increase the budget" | "I'd check frequency and whether the winning ad is fatiguing first" |
| Talks about CPM and CTR | Talks about cost per new customer and what that customer is worth |
Creative matters most, and I learned that on the client side. At Healthify Store, what moved results was creative depth: many ideas tested, each explaining one thing clearly. For whey protein we ran doctor-led UGC on why protein matters, a family-led version of the same idea, and a Gen Z style video. Each found a different kind of buyer, and we rotated targeting and creative around what each told us. No UGC ran longer than a month, and there was always a control creative to beat.
Meta ads bring the first order. What happens after it decides whether the ad was worth paying for. I show that path in my digital marketing interview questions guide.

Meta ads interview questions for freshers
1. What are Meta ads?
Paid ads on Meta's apps: Facebook, Instagram, Messenger, WhatsApp (as a destination) and the Audience Network of partner apps. You build and run them in Meta Ads Manager. "Facebook ads" is the older name, and interviewers use both.
2. What is the structure of a Meta ads campaign?
Three levels. The campaign holds the objective. The ad set holds the audience, placements, budget (unless the campaign controls it), schedule and optimisation goal. The ad holds the creative, copy, link and call to action.
What they're listening for. That you know which decision lives at which level. Candidates who say "I set the targeting in the ad" lose the room.
3. What are the six campaign objectives?
Awareness, Traffic, Engagement, Leads, App promotion and Sales. Meta simplified the older list (Brand awareness, Reach, Conversions, Catalogue sales, Store traffic and the rest) into these six in 2022. A D2C brand selling online mostly uses Sales.
4. Which objective would you choose for a D2C brand that wants orders?
Sales, optimised for purchases, with the Pixel and Conversions API sending purchase events. Choosing Traffic because clicks look cheaper is the classic mistake. Meta then finds people who click, not people who buy.
5. How does the Meta ad auction decide which ad wins?
Meta ranks ads by total value, which combines three things: your bid, the estimated action rate (how likely this person is to do what you optimise for), and ad quality. A better ad can beat a higher bid. That's why creative quality lowers your costs.
6. What is CPM, and why does it change?
Cost per 1,000 impressions. ₹40,000 spent for 2,00,000 impressions is a CPM of ₹200. It rises when more advertisers compete for the same people, like Diwali and big sale weeks, and when your ads are rated lower quality.
7. What is the difference between CTR (all) and link CTR?
CTR (all) counts every click, including likes, profile taps and "see more". Link CTR counts only clicks that go to your destination. For a sales campaign, link CTR is the one that matters.
8. How do you calculate CPC and CPA?
CPC is spend divided by link clicks. CPA (cost per acquisition, or cost per result) is spend divided by conversions. ₹30,000 for 1,500 link clicks and 60 purchases is a CPC of ₹20 and a CPA of ₹500.
9. What is ROAS?
Return on ad spend: revenue divided by ad spend. ₹90,000 of revenue from ₹30,000 of spend is a ROAS of 3x. Write it as 3x or 3.0. Some guides multiply it by 100 and call it 300%, which confuses it with ROI.
10. What are placements, and what are Advantage+ placements?
Placements are where ads show: Facebook and Instagram Feeds, Stories, Reels, Explore, Messenger, the Audience Network and others. Advantage+ placements (once called automatic placements) let Meta spread the budget across them. It's the right default for most accounts. Exclude a placement only when data shows it wastes money.
11. What is Meta Business Suite, and what is a business portfolio?
Meta Business Suite is where a business manages its Page, Instagram account, ads, inbox and settings. The business portfolio is the container that owns the Pages, ad accounts, Pixels and people. It used to be called Business Manager.
12. What is the Meta Pixel?
A piece of code on your website that tells Meta what visitors do: page views, product views, add to cart, purchases. Meta uses it to report results, optimise delivery and build audiences. It used to be called the Facebook Pixel, and its events now sit in a dataset in Events Manager.
13. What are standard events?
Actions Meta has predefined names for, like PageView, ViewContent, AddToCart, InitiateCheckout, Purchase, Lead and Schedule. Using standard names lets Meta optimise for them directly. Custom events are for anything else.
14. What is a custom audience?
People who already know you: website visitors (from the Pixel), customer lists you upload, people who engaged with your Instagram or videos, and app users. Used for retargeting, and for excluding people you don't want to pay for again, like recent buyers.
15. What is a lookalike audience?
People who resemble a source audience, like your best customers. You pick a country and a size, from 1% (closest match) to 10% (broader). The source needs at least 100 people from one country. Today Meta also uses lookalikes as a signal inside Advantage+ audience.
16. What is the learning phase?
The period after you launch an ad set, or make a significant edit, when Meta is still working out who to show it to. Performance is less stable and usually costs more. An ad set usually exits after about 50 results in the week after its last significant edit.
17. What do "Learning limited" and "Active" mean in the delivery column?
"Active" means the ad set is running normally. "Learning limited" means it isn't getting enough results to exit the learning phase, usually because the budget is too small, the audience too narrow, or the optimisation event too rare. It isn't a penalty. It's a hint to consolidate.
18. How does Meta review ads?
Every ad is checked against Meta's Advertising Standards before it runs, usually within 24 hours. Rejections mostly come from before-and-after claims, personal attributes ("Are you overweight?"), misleading claims and restricted products. You can request another review.
19. What are the Meta Blueprint certifications?
Meta's exams for marketers. The current list includes Digital Marketing Associate (100-101), Marketing Science Professional, Creative Strategy Professional, Media Planning Professional, Media Buying Professional (410-101) and Community Management. A fresher can start with the Associate exam. It helps, but a small campaign you ran yourself helps more.
20. What is the difference between boosting a post and running an ad from Ads Manager?
A boost promotes an existing post with a few simple settings. Ads Manager gives you the full control: objective, optimisation event, placements, audiences, budget rules and testing. Boosts suit engagement goals. Sales campaigns belong in Ads Manager. (Power Editor, which some guides still mention, was folded into Ads Manager years ago.)
Audiences and creative questions
21. What is Advantage+ audience?
Meta's default way of finding people for an ad set. You can give suggestions (age, interests, custom audiences, lookalikes) and Meta may go beyond them when it predicts better results. You can still set hard limits, like location, minimum age and excluding custom audiences.
22. Should a D2C brand still use detailed interest targeting?
Rarely as the main lever. Broad targeting with strong creative usually wins once the Pixel has enough purchase data, because the creative itself tells Meta who it's for. Interests are still useful as suggestions for a new account, or for a niche product with little data.
23. Can you exclude interests in 2026?
No. Meta removed detailed targeting exclusions in 2025, so you can no longer exclude interests or behaviours. You can still exclude custom audiences, like recent buyers or people who already converted. Guides that tell you to "exclude competitor interests" are out of date.
24. What does "creative is the new targeting" mean?
Meta's delivery system decides who sees an ad largely from what the ad shows and says. A video of a mother cooking for her kids reaches different people from a gym video, even with the same targeting. So instead of building audiences, you build different creative angles and let each find its buyers.
25. What is Andromeda?
The ad retrieval system Meta introduced in late 2024. It's the first stage of picking which ads might be shown to a person, from millions of candidates. In practice it rewards accounts that give Meta many genuinely different creatives, not ten copies of one idea with a new colour.
26. What is creative fatigue, and how do you spot it?
When the same people have seen an ad too often and it stops working. Signs: rising frequency, falling CTR, rising CPA, and comments repeating themselves. Fix it with a new idea, not a new background colour.
27. What is frequency, and what's a healthy number?
The average number of times each person saw your ad in the period. There is no universal right number. Watch the trend. If frequency climbs and CTR falls at the same time, the ad set is saturating. For a retargeting audience, a higher frequency is normal.
28. How do you structure a creative test?
One variable at a time, against a control. Test the idea (the angle or hook) before the format, and the format before small details. Give each test enough budget to reach a decision, and decide in advance what result counts as a win, like a lower cost per purchase with similar order value.
What they're listening for. A control creative. Teams that test without one are just changing things.
29. What is a control creative?
Your current best ad, the one every new creative has to beat. At Healthify Store we always had one running, and every new UGC went live against it. Replace the control only when a new ad beats it on cost per purchase.
30. What is UGC, and why does it work in ads?
User-generated content: videos that look like they were made by customers or creators, not by the brand. It works because it looks like the rest of the feed and feels like a recommendation. Brands now brief creators to make UGC-style ads on purpose.
31. How many ideas should one creative carry?
One. The ads that worked best for us explained one thing clearly. Not too much information. A whey protein ad that tries to cover taste, price, protein content and a discount at once usually loses to one that only explains why protein matters.
32. How would you build different creative angles for the same product?
Change who is speaking and why it matters to them. For whey protein we ran a doctor explaining why protein is important, a family-led version, and a Gen Z style video. Each reached a different kind of buyer, and the results showed us which audience responded to which voice.
33. How often should you refresh creatives?
When they fatigue, not on a calendar. At Healthify Store we never let a UGC run longer than a month. Bigger budgets burn through creative faster.
34. What are Advantage+ creative enhancements?
Automatic changes Meta can make to your ad, like adjusting brightness, adding music, cropping for different placements or testing text variations. Review each one. Some help reach, and some change your brand's look in ways you wouldn't approve.
35. What are Advantage+ catalogue ads?
Ads that pull products from your catalogue and show each person the products they're most likely to buy, often ones they viewed. They used to be called dynamic product ads. They need a clean product feed and Pixel events with matching product IDs.
36. What are Partnership ads?
Ads that run from a creator's handle and your brand's handle together, using the creator's post or content made for you. They used to be called branded content ads. They work because people trust the creator's name more than the brand's.
37. What is the hook, and why do the first three seconds matter?
The opening that stops the scroll. On Reels and Stories, most people decide in the first second or two whether to keep watching. A strong hook names the problem or shows the result straight away. Track hook rate (3-second views divided by impressions) to compare openings.
38. What's the difference between hook rate and hold rate?
Hook rate shows how many people stopped. Hold rate (often ThruPlays or 15-second views divided by 3-second views) shows how many stayed. A high hook rate with a low hold rate means the opening works but the body loses them.
39. What are click-to-WhatsApp ads?
Ads whose button opens a WhatsApp chat with the business instead of a website. They work well in India, where people are comfortable asking questions on WhatsApp before buying. You need a WhatsApp Business number connected to the Page, and someone (or a bot) to reply fast.
40. What does the Facebook 20% text rule say today?
Nothing. Meta dropped the 20% text rule in 2020. Less text usually still performs better, but an ad with more text is no longer rejected for it. Some guides still teach the rule.
Pixel, Conversions API and attribution questions
41. What is the Conversions API (CAPI)?
A way to send events to Meta from your server instead of the visitor's browser. Browsers block or lose many Pixel events (ad blockers, iOS privacy, slow pages), so a server copy makes tracking more complete. Most brands run both, Pixel and CAPI together.
42. If you run the Pixel and CAPI together, how do you avoid counting a purchase twice?
Deduplication. Send the same event name and the same event ID from both. Meta matches the browser's event ID with the server's event_id and keeps one. Events are deduplicated within 48 hours.
What they're listening for. The words "event ID". It's the most common gap in candidates who say they've "set up CAPI".
43. What is Event Match Quality?
A score from 0 to 10 in Events Manager that shows how well the customer information sent with your events (email, phone, IP address, browser ID and so on) lets Meta match them to accounts. Higher match quality means better attribution and optimisation.
44. What is advanced matching?
Sending hashed customer details, like email and phone number, with Pixel events, so Meta can match more events to people. Automatic advanced matching picks them up from forms on your site. Your privacy notice should say you do this.
45. What is an attribution setting?
The rule for which conversions Meta credits to your ads. Under the standard model you choose from click-through (1 or 7 days after a link click), view-through (1 day after an impression) and engage-through (1 day after a non-link interaction, or a video watched for 5 seconds). 7-day click and 1-day view is a common setting.
46. What changed in Meta's click attribution in 2026?
Click-through now counts only link clicks. Conversions after other clicks, like likes, shares and saves, are counted as engage-through instead. So reported results can drop slightly without anything getting worse.
47. What is the difference between standard and incremental attribution?
Standard attribution credits conversions that happened within your chosen window after someone saw or clicked an ad. Incremental attribution optimises and reports on conversions Meta predicts were caused by the ad. Results under the two models can't be compared directly.
48. Why do Meta's numbers never match Shopify or Google Analytics?
Each tool counts differently. Meta credits view-throughs and conversions across devices. Analytics usually credits the last click. Shopify counts every order, including ones no ad touched. Pick one source of truth for business decisions, and use Meta's numbers to compare ads with each other. (Facebook Analytics, which some guides list as a tool, shut down in 2021.)
49. What is ROAS, and what is break-even ROAS?
ROAS is revenue divided by ad spend. Break-even ROAS is the ROAS at which you make no profit, which is 1 divided by your contribution margin before ads. If 40% of each sale is left after product, shipping, payment fees and returns, break-even ROAS is 1 ÷ 0.40 = 2.5x.
50. Is a 3x ROAS good?
It depends on the margin. At a 50% margin, 3x is profitable. At 30%, break-even is about 3.3x, so 3x loses money on the first order. The right answer always asks for the margin first.
51. What is blended ROAS (or MER)?
Total revenue divided by total marketing spend, across all channels. It ignores attribution arguments and shows whether marketing as a whole is paying back. On the accounts I've run, Meta's own attribution showed about 3x ROAS. Counted together with retargeting existing customers, it came to about 4x.
52. What does iOS 14 have to do with Meta ads?
Apple's App Tracking Transparency (from iOS 14.5 in 2021) lets people refuse tracking across apps. Meta lost a lot of signal, shortened attribution windows (the 28-day windows went) and leaned on modelling. It's the reason CAPI and advanced matching became standard.
53. Do you still need to rank 8 events for Aggregated Event Measurement?
No. That was the 2021 setup. Meta stopped requiring advertisers to choose and rank 8 events in 2023. Guides that tell you to rank events are out of date.
54. What is a conversion lift study?
A test where Meta splits people into a group that can see your ads and a holdout that can't, then compares conversions. The difference is what the ads actually added. It's the most honest answer to "would these people have bought anyway?"
55. How would you measure what Meta adds without Meta's own tools?
A geo or time holdout. Pause or cut spend in some cities, or for a period, and compare orders against a matched control. It's rough, but it tells a founder more than attributed ROAS does.
56. What are the ad relevance diagnostics?
Three rankings shown for each ad against ads competing for the same audience: quality ranking, engagement rate ranking and conversion rate ranking. They replaced the old "relevance score" in 2019. Use them to diagnose an ad, not as a goal.
57. What is the breakdown effect?
When Meta shifts budget to the placement, age group or ad that looks more expensive per result in the breakdown, and it's still the right call. Meta optimises for the overall result. Cutting the "expensive" segment often raises your total cost.
58. What is UTM tagging, and why use it on Meta ads?
Adding parameters like utm_source=facebook and utm_campaign to your ad links, so Google Analytics and your store can see which campaign and ad brought a visit. Meta's URL parameters can fill in campaign and ad names automatically.
59. Which numbers should a weekly Meta ads report show?
Spend, purchases, cost per purchase, ROAS against break-even, new versus returning customers, and the top and bottom creatives with a reason. Then one decision for next week. A report full of CPM, CTR and reach with no decision is noise.
60. What does "Instagram views" mean in reporting now?
Meta replaced impressions with views as the main reach metric for Instagram content. Views count each time the content is shown, including repeats. Guides that report "Instagram impressions" are using the old metric.
Budgets, bidding and scaling questions
61. What is Advantage+ campaign budget?
A budget set at the campaign level that Meta spreads across ad sets in real time, spending more where results are best. It used to be called campaign budget optimisation (CBO). Meta recommends it for campaigns with at least two ad sets.
62. When would you use ad set budgets instead?
When you need to guarantee spend on something specific: a new creative test, a product launch, or a retargeting ad set that would otherwise get starved. Ad set budgets give control, while campaign budgets usually give efficiency.
63. What are Advantage+ sales campaigns?
Meta's most automated setup for the Sales objective, with Advantage+ audience, placements and budget turned on together. They used to be called Advantage+ shopping campaigns. You supply strong creative and good conversion data, and Meta does most of the targeting.
64. What are the main bid strategies?
Highest volume (Meta gets the most results for the budget), cost per result goal (Meta aims to keep average cost near your target), ROAS goal (Meta aims to keep ROAS above your floor), and bid cap (a hard maximum bid in each auction). Most accounts start with highest volume.
65. When would you use a cost per result goal?
When you know the most you can pay for a result and still make money, and you'd rather spend less than spend at a loss. Set it too low and the campaign barely spends. A common approach is to start near your current average cost and tighten slowly.
66. How much daily budget does an ad set need to exit learning?
Work backwards from about 50 results a week. If your cost per purchase is ₹600, that's 50 × ₹600 ÷ 7, about ₹4,300 a day for one ad set optimising for purchases. If that's too much, consolidate ad sets or optimise for an earlier event like add to cart.
67. What counts as a significant edit?
Changes that make Meta relearn, like changing targeting, the optimisation event or creative, adding a new ad, pausing for a week or more, or making a large budget change. Small budget changes don't usually reset learning. Batch your edits instead of tweaking daily.
68. How do you scale a winning campaign?
Two ways. Vertical: raise the budget on what's working, in steps, watching cost per purchase. Horizontal: take the winning idea into new creatives, new angles and new audiences. Most real scaling comes from new creative, because a single ad fatigues as spend grows.
What they're listening for. That scaling needs more creative, not just more budget.
69. Why does CPA usually rise when you scale?
The cheapest buyers come first. As you spend more, Meta has to reach people who are less ready to buy, so each extra purchase costs more. The question is whether the extra customers are still profitable, not whether average CPA stayed flat.
70. What is a reasonable budget split between prospecting and retargeting?
Most of it in prospecting, because retargeting audiences are small and fill up fast. If retargeting takes a large share, you're probably paying for orders you'd have got anyway. Check it with new versus returning customer reporting.
71. How do you stop paying for customers you already have?
Exclude recent buyers (a custom audience from your store or Pixel) from prospecting, and use segment reporting for new versus existing customers. Bring them back through retention channels like WhatsApp and email, which cost far less per order than ads.
72. What is a lifetime budget, and when is it useful?
A total budget for the whole campaign instead of a daily one. It's useful for a fixed sale period, like a 5-day festive sale, because Meta can spend more on the days that convert best. You can also schedule ads to run only at certain hours.
73. How would you plan budgets for a Diwali sale?
Start warming up two to three weeks earlier with awareness and engagement, so you have people to retarget. Expect CPMs to rise in sale week. Launch new sale creatives early enough to exit learning. Set a lifetime budget for the sale window, and keep retention messages going to past buyers, who convert cheapest.
74. What is the A/B test tool in Meta?
A test that splits an audience into groups with no overlap, each seeing one version (creative, audience, placement or optimisation), and reports which won with a confidence level. It used to be called split testing. Use it for big questions. Use normal creative testing for everyday iteration.
75. How do you decide when to kill an ad?
Before launch, set a spend limit: for example, if it has spent two to three times your target cost per purchase with no purchase, pause it. Judge on purchases and cost, not on early CTR alone, and give the ad set time to deliver before calling it.
76. What is the attribution setting's effect on optimisation?
It also tells Meta which conversions to optimise for. A 7-day click setting tells Meta to find people likely to buy within a week of clicking. Changing it changes delivery and reported numbers, so don't change it mid-test.
77. What is dayparting, and does it work on Meta?
Running ads only at certain hours. On Meta it needs a lifetime budget, and it's rarely worth it, because Meta already spends more when people convert. It can help for a business with phone-based sales that only answers calls in office hours.
78. What is Opportunity Score?
A score from 0 to 100 in Ads Manager, with recommendations Meta says can improve performance, like turning on Advantage+ features or fixing tracking. A high score doesn't guarantee results. Treat each recommendation as an idea to test.
79. What is the Audience Network, and should you use it?
Meta's network of partner apps and sites. It reaches people cheaply, but quality varies. Leave it on inside Advantage+ placements for sales campaigns, where Meta judges it by purchases. Watch it closely on lead campaigns, where cheap form fills can be junk.
80. How do you calculate how much you can afford to pay for a customer?
Use the profit the customer brings, not just the first order. If the first order leaves ₹500 of contribution and a typical customer orders again within 6 months for another ₹400, you can afford to pay more than ₹500, because retention pays back the rest. This is where Meta ads and CRM become one decision.
D2C scenario questions for 2 to 5 years
81. Your cost per purchase doubled overnight. What do you check, in order?
- Tracking. Did Pixel or CAPI events break, or did the website change?
- The website. Is checkout or payment failing?
- The calendar. Is it a sale week where CPMs jumped for everyone?
- Edits. Did someone make significant edits and reset learning?
- Creative. Did the main ad fatigue?
Fix the first broken thing before touching budgets.
82. ROAS looks great on Meta, but the founder says sales haven't moved. What's going on?
Probably attribution. Meta may be crediting orders that would have happened anyway, often from returning customers or people who were already searching for the brand. Check new versus returning customers, compare blended revenue against spend, and propose a holdout test.
83. Half the orders are COD and a lot get returned. How does that change your Meta strategy?
Optimise for what makes money. Track RTO (return to origin) by campaign and creative, and judge ads on delivered orders, not placed orders. Send only delivered or prepaid purchases back to Meta as the main event if you can, and nudge COD buyers to prepay with a small discount on WhatsApp after the order.
84. How would you launch a new D2C brand on Meta with ₹2 lakh for the first month?
One sales campaign, broad targeting, three to five genuinely different creative angles, and a budget large enough per ad set to learn. Install the Pixel and CAPI before spending. Expect the first two weeks to be expensive. Set up a WhatsApp welcome flow so first-time visitors get followed up for free.
85. The best ad has run for six weeks and is slowing. The founder doesn't want to change it. What do you do?
Show the data: rising frequency, falling CTR, rising cost. Then launch new ads against it as a test, with it still running as the control. Don't kill a winner on opinion. Let a new ad beat it.
86. How would you brief a UGC creator for a protein product?
One idea per video. Tell them who they're talking to, the single point to land (for example, why protein matters for a working parent), the hook in the first two seconds, and what must not be said (no medical or before-and-after claims). Ask for three openings so you can test hooks separately.
87. The client wants to target competitors' customers. What do you say?
You can't target a competitor's customers directly, and detailed targeting exclusions are gone too. Compete through creative instead. Make the ad answer the reason people choose the competitor, and let broad delivery find them.
88. CPMs rose 40% in sale week, and CPA rose with them. Is the campaign broken?
Not necessarily. Everyone pays more in sale weeks. Check whether conversion rate and order value held up. If revenue per rupee spent still clears break-even, keep spending. If it doesn't, shift spend to retargeting and retention, which hold up better.
89. How would you split work with a performance marketing agency?
The brand owns the numbers that define success (margins, break-even ROAS, new customer targets), the creative direction and the tracking. The agency runs buying, testing and reporting against those numbers.
90. A lead gen campaign gets cheap leads, but sales says they're junk. What do you change?
Make the form harder in a useful way. Switch to a higher-intent form type with a review step, add a qualifying question, and optimise for a later event (like a qualified lead sent back through CAPI) instead of form submits. Cheap leads that don't convert are expensive.
91. Click-to-WhatsApp ads get lots of chats but few sales. What do you check?
Response time first: a chat answered an hour later converts much worse than one answered straight away. Then the first reply (does it answer the question and show the product?), and whether there's a follow-up for people who went quiet. Often the ad is fine and the chat process isn't.
92. How do you decide between more Meta spend and investing in retention?
Compare the cost of a new customer with the cost of a repeat order. If repeat orders cost a fraction through WhatsApp and email, fix retention first, because it raises what every new customer is worth. Then Meta can afford to pay more per customer.
93. How do Meta ads and CRM work together?
Meta brings the first visit and first order. CRM (WhatsApp, email, SMS, push) turns those people into repeat buyers. Pixel audiences and customer lists connect them: exclude buyers from prospecting, retarget non-buyers, and send customer data back so Meta finds more people like your best customers.
94. Your Event Match Quality for Purchase is low. How do you fix it?
Send more customer details with the event: hashed email and phone number from checkout, external ID, IP address and browser ID through CAPI. Make sure the Pixel and CAPI share event IDs. Then check the score again after a few days of data.
95. A competitor launched with a 40% discount, and your conversion rate fell. What do you do?
Don't match the discount by reflex. Lean on what you have that they don't: reviews, faster delivery, a better guarantee. Test a creative that answers the price question directly. Use retention offers for existing customers, who are most at risk of switching.
96. How would you test whether a 10% discount is worth it?
Run the same creative with and without the offer, in a proper A/B test, and compare profit per order, not conversion rate. A discount that raises conversion by 15% but cuts margin by a third usually loses money.
97. You inherit an account with 40 active ad sets and a small budget. What do you do?
Consolidate. 40 small ad sets can't each reach 50 results a week, so most will sit in learning forever. Merge into a few ad sets with broad targeting, move the best creatives into them, and use a campaign budget.
98. The founder asks why you need more creative every month. How do you explain it?
Creative is how Meta finds new buyers now. Each new idea reaches a new group of people, and each ad wears out as the same people see it again. On the accounts I've run, no UGC ran longer than a month.
99. How would you report Meta results to a founder in one slide?
Spend, new customers, cost per new customer, first-order ROAS against break-even, what those customers have spent since, and one decision. Founders care whether the money came back and what you'll do next week.
100. What would you do in your first 30 days on a new Meta account?
Week 1: audit tracking (Pixel, CAPI, deduplication, match quality) and learn the margins. Week 2: clean up the structure and set a control creative. Weeks 3 and 4: launch a creative testing routine and agree the reporting with the founder. Change nothing big before you trust the data.

Take-home Meta ads assignment: a sample with a marking guide
Many D2C brands send a task after the first round. Here's a typical one, with how I'd mark it.
The brief. "A D2C protein brand spends ₹3 lakh a month on Meta at a reported ROAS of 2.8x. Contribution margin before ads is 40%. 35% of orders are COD, and 20% of COD orders are returned. Here's an export of the account. In two pages, tell us whether Meta is profitable, what you'd change in the next 30 days, and what creatives you'd test."
| What a strong answer does | Marks |
|---|---|
| Works out break-even ROAS (1 ÷ 0.40 = 2.5x) and adjusts the 2.8x for COD returns before judging it | 20 |
| Separates new from returning customers and questions what Meta takes credit for | 20 |
| Checks tracking: Pixel and CAPI, deduplication, and which purchase event is sent | 20 |
| Proposes a creative plan with distinct angles, a control and a refresh rhythm | 20 |
| Connects ads to retention: excluding buyers, a COD-to-prepaid nudge, repeat orders | 20 |
What loses marks. Reporting CTR and CPM as results, "increase the budget" with no reason, and taking Meta's ROAS at face value.
Performance marketing interview questions
If the job title says performance marketing executive or manager, expect most of the questions above plus a few on the business around the ads. The ones I'd ask:
- How do you work out break-even ROAS, and what's ours likely to be? (see Q49)
- How do Meta and Google Ads split the work for a D2C brand? Google catches demand that already exists. Meta creates new demand through creative.
- What's the difference between ROAS and ROI? ROAS is revenue per rupee of ad spend. ROI counts profit after all costs.
- How do you measure what ads add beyond what would have happened anyway? (see Q54 and Q55)

FAQ
How should I prepare for a Meta ads interview? Learn the current names (Advantage+ sales campaigns, Advantage+ campaign budget, business portfolio), practise the CPA, ROAS and break-even maths out loud, and run a small campaign of your own, even with ₹5,000. Be ready to explain one result in rupees.
What Meta ads questions are asked of freshers? The campaign structure, the six objectives, how the auction works, CPM, CTR, CPC, CPA and ROAS, the Pixel and standard events, custom and lookalike audiences, and the learning phase.
What is asked in a Meta ads interview for 2 to 5 years of experience? Mostly scenarios. Why CPA rose, how you scale, how you test creative, how you handle COD and returns, how you set up CAPI and deduplication, and how you report to a founder, plus a take-home account audit.
Are Facebook ads and Meta ads the same thing? Yes. Meta is the company that owns Facebook, Instagram, Messenger and WhatsApp, and the ads for all of them are run from Meta Ads Manager. "Facebook ads" is the older name.
Is the Meta Blueprint certification worth it? It shows you know the basics and helps a fresher stand out. Interviewers care more about whether you can explain real results and the maths behind them.
Is there a Meta ads quiz I can take? Yes. The mock interview on this page has 50 questions across five sections, picks 10 at a time, and tells you why each answer is right or wrong.
What does a Meta ads specialist do? Plans, launches and optimises Facebook and Instagram campaigns: briefs creatives, sets up tracking, manages budgets and bids, tests, and reports results against business targets like cost per new customer.
What is the salary of a Meta ads executive in India? It varies widely by city, company and experience, from entry-level agency roles to well-paid in-house roles at funded D2C brands. Candidates who can show real results and profit-based thinking move up fastest.
Open to CRM and retention roles as well as paid ads? Fewer candidates go for them, and the two jobs fit together. My CRM Career Launchpad has nine self-study kits for a first CRM job, free for the first 100 learners.
