Meta·Software Engineer·Onsite - Behavioral / Leadership

Jun 2026
Behavioral round at Meta for a solutions architect role. Just one question from what I can tell, but it was a classic adaptability prompt that required a solid story.
  • Describe a situation where you had to reverse or significantly change a decision you had already made.

“I had a decent story ready but stumbled a bit on explaining why the original decision seemed right at the time.”

Meta·Product Manager·Onsite - Product Sense / Strategy

Jun 2026
Got a product design question at Meta about the fake news problem on Facebook. Pretty open-ended, which sounds fun until you're actually sitting there trying to figure out where to even start.
  • How would you design a product to tackle the fake news problem on Facebook?

“I went straight into solutions mode and that was probably the wrong call.”

Meta·Product Manager·Onsite - Product Sense / Strategy

Jun 2026
PM interview at Meta with a product design question about an everyday physical object. Short on details but the question itself was pretty open-ended and caught me a bit flat-footed.
  • How would you design a refrigerator for Meta?

“I spent way too long trying to figure out what Meta even wants with a refrigerator before I just picked a user group and ran with it.”

Meta·Software Engineer·Technical Phone Screen

Jun 2026
Meta SWE interview with a multi-level coding problem that built up into a full money transfer system. The last level was the most interesting, requiring pending transfers with expiration and refund logic.
  • Design a money transfer system between users where the sender initiates a transfer (deducting the amount immediately and creating a pending transfer with an expiration), the recipient must accept before it expires to receive the funds, and any unaccepted transfers are automatically refunded. Only completed (accepted) transfers should count toward transaction totals.

“This is where the problem got genuinely tricky.”

Meta·Data Scientist·Technical Phone Screen

Jun 2026
Meta DS interview with a meaty experiment analysis question. The whole thing revolved around one scenario but it had a lot of layers to unpack, more than I expected from a single prompt.
  • An ad-ranking algorithm shows a 5% overall CTR lift but a 100% lift specifically for Indian males aged 18-24. What could explain that gap, how would you confirm the lift is real and not noise, and what else would you look at before a global rollout?

“This is the kind of question where you think you're doing well and then realize halfway through you forgot to mention Simpson's paradox.”

Meta·Machine Learning Engineer·Hiring Manager Screen

Jun 2026
Did a screen for an ML engineer role at Meta. Just one question about recent work history, pretty standard stuff.
  • Walk me through your work experience over the past year.

“Pretty much a resume walkthrough.”

Meta·Data Scientist·Onsite - Product Sense / Strategy

Jun 2026
Integrity-focused DS case at Meta, all about designing a severity metric suite for harmful content. Heavy on measurement theory and tradeoffs, less coding. Walked out feeling like I'd spent an hour arguing with myself about what 'harm' even means.
  • Design a metric or metric suite to measure the severity of harmful/policy-violating content on a large social platform. You have impression logs, content metadata, partial human-review labels, and ML classifier scores. What do you propose?
  • The team wants to use View Prevalence (views of violating content divided by all views) as the primary KPI. What are the pros and cons?
  • Walk through the key tradeoffs in choosing and optimizing these metrics. Cover at least: user safety vs. engagement, precision vs. recall, reporting robustness vs. sensitivity to change, and fairness across regions and languages.
  • Recommend a final metric suite. Which metric is the primary KPI, what are your diagnostic metrics, and what are your guardrails?
  • A new classifier improves recall by 15% in Spanish and Portuguese, and your severity-weighted metric rises as a result. How do you explain to leadership whether the platform actually got worse or your measurement improved?
  • Would you use the weekly primary KPI to trigger on-call alerts for harm spikes, or would you design a separate alerting signal? What would that signal look like?
  • How would you set severity weights across violation policy classes in a defensible way, and how would you detect if those weights are driving misleading movements in the KPI?
  • An intervention reduces your primary metric but you suspect creators are migrating to a less-instrumented surface like DMs. How do you detect and account for surface displacement?

“This is the kind of question where jumping straight to a single ratio gets you killed.”

Meta·Product Manager·Onsite - Product Sense / Strategy

Jun 2026
Product sense round at Meta for a PM role. One question, but it had enough layers to keep me busy for the full session.
  • How would you design a bookshelf specifically for children? Walk through who you're designing for, what problems they face, the core design principles you'd apply, what you'd ship first, and how you'd measure whether it worked.

“I spent way too long on the user definition part.”

Meta·Software Engineer·Recruiter / HR Screen

Jun 2026
Interviewed for a product analyst role at Meta, just the one question about career motivation. Short and a bit underwhelming honestly.
  • What drew you to a career in analytics?

“Pretty standard opener but I still fumbled it a bit.”

Meta·Software Engineer·Technical Phone Screen

Jun 2026
Meta SWE coding round with a range overlap problem. Pretty standard stuff but the edge cases are where they actually test you.
  • Given two range objects each with a start and end integer, write a function to determine whether the two ranges overlap.

“Looked simple and I almost wrote a four-case if-statement before catching myself.”
