FAQ

Do I need to know the exact numbers for latency and equity to pass the Meta FAIR interview? Yes. The panel expects a latency target ≤ 200 ms and will compare your equity request to the standard 0.07 % range for senior FAIR roles. Deviating from those numbers without justification triggers a “trade‑off missing” flag.

What if I’m strong on algorithms but weak on system diagrams? The interview is a systems round; a weak diagram is a “no‑hire” signal even if your algorithmic score is 9 / 10. Meta’s rubric scores diagrams separately; a 0 in the diagram axis forces a reject.

Can I recover from a poor first impression in the multi‑agent design interview? Rarely. In the Meta FAIR loop, the HC vote is set after the first 30 minutes; a bad first impression (e.g., missing the contract annotation) leads to a 4‑3 no‑hire even if later answers improve. The panel does not revisit the scorecard.amazon.com/dp/B0GWWJQ2S3).
