FAANG / Big Tech

Most of these Meta write-ups come from Software Engineers (1,194), then Data Scientists (489) and Product Managers (453). The most reported rounds are the technical phone screen (1,190), the product sense round (466), the system design round (255) and the behavioral / leadership round (205).

Meta·Performance Engineer·Technical Phone Screen

Apr 2026
Meta Production Engineer loop, and this one was almost entirely a single algorithmic problem about pairing dinosaur crossings across two sensor lines and computing speeds. PE-track specific apparently, so don't expect to see this if you're not in that loop. The follow-ups got progressively more annoying.
  • You have two sensor lines a fixed distance apart. Each line records timestamps when a dinosaur crosses it. Pair up crossings from line 1 and line 2 that represent the same dinosaur (within a reasonable time window), then compute the speed for each pair. Follow-ups include filtering by a speed threshold and handling multiple dinosaurs in flight simultaneously.

“My first instinct was brute force, match every line-1 timestamp against every line-2 timestamp and pick the closest.”

Meta·Technical Program Manager·Onsite - Behavioral / Leadership

Apr 2026
Behavioral screen for a TPM role at Meta, just the one question about handling critical feedback. Pretty standard but it's the kind of thing you can fumble if you don't have a clean story ready.
  • Describe a situation where your manager gave you negative feedback and explain how you responded to it.

“I had a story ready but partway through I realized it made me sound defensive rather than growth-oriented, so I kind of pivoted mid-answer which probably looked awkward.”

Meta·Software Engineer·Onsite - Behavioral / Leadership

Apr 2026
Three behavioral questions for a Software Engineer role at Meta. Nothing technically tricky but the questions themselves have some teeth if you haven't thought them through before.
  • When stakeholders across different teams have conflicting priorities or disagree on requirements, how do you handle getting everyone aligned?
  • What's the biggest professional mistake you've made, and what came out of it?
  • Tell me about a time you failed to deliver something you were responsible for. What happened and how did you recover?

“This one felt like it was testing whether you actually do the messy work or just escalate.”

Meta·Software Engineer·Onsite - Coding / Algorithms

Apr 2026
Meta coding round, one problem the whole session. The question looked like a knapsack variant but the twist was you had to return the actual subset, not just the count. That detail changed everything about how you had to approach it.
  • Given a list of items each with a positive weight and a capacity W, find the maximum number of items whose total weight fits within W and return the actual subset of item IDs, not just the count.

“I went straight for DP and got maybe halfway through before realizing reconstructing the subset would be a mess.”

Meta·Software Engineer·Technical Phone Screen

Apr 2026
Meta SWE screen, one coding problem about shipping capacity. Pretty standard stuff, nothing too wild.
  • Given a list of package weights and a number of days D, find the minimum ship capacity needed to deliver all packages within D days.

“Binary search on the answer.”

Meta·Software Engineer·Onsite - Coding / Algorithms

Apr 2026
Meta SWE coding round, just the one question about maze pathfinding. Pretty standard graph traversal stuff, nothing that should trip you up if you've done any BFS or DFS prep.
  • Given a 2D grid where 0 is open and 1 is a wall, determine if there's a path from a start cell to a target cell using 4-directional movement.

“Classic BFS/DFS maze problem.”

Meta·Software Engineer·Technical Phone Screen

Apr 2026
Meta SWE interview with a single coding problem. Not much to report beyond the problem itself.
  • Given a string of parentheses, what is the minimum number of parentheses you need to add to make it valid?

“Classic stack-based problem.”

Meta·Software Engineer·Hiring Manager Screen

Apr 2026
Went through a Meta interview focused on people management, specifically around how you think about promoting someone into a manager role. Pretty niche question if you're not expecting it.
  • How do you handle promoting someone into a manager position?

“I went straight to the logistics side of it, like how you structure the transition and set expectations, but I think they wanted more about how you identify readiness in the first place.”

Meta·Product Manager·Hiring Manager Screen

Apr 2026
Meta PM interview, one question about how you'd handle a sudden directive to prioritize travel as a focus area. Short but not easy.
  • A manager tells you the team needs to shift focus to travel. How do you approach that?

“I started talking about user research and segmentation which felt right but I could tell I was dancing around the actual structure they wanted.”

Meta·Product Manager·Onsite - Product Sense / Strategy

Apr 2026
Meta PM interview, product sense round focused on monetization. Just the one question but it had a lot of moving parts and I left feeling like I only scratched the surface.
  • You're a PM on Instagram Reels. How would you define and measure the success of rolling out ads to the feature?

“I jumped straight to engagement metrics and the interviewer kind of waited, like they wanted me to slow down.”
