FAQ

Why do Meta interviewers penalize “just use a queue” even if the candidate knows Kafka?
Because the phrase signals a shallow trade‑off analysis; the rubric treats it as a “Complexity — High” flag. Candidates who name Kafka but then explain partitioning, replication factor, and latency budgets avoid the penalty.

Can I succeed in the system design round without mentioning specific latency numbers?
No. The debrief from the Q2 2026 Instagram loop shows that a candidate who omitted latency was voted No Hire 4‑2. Meta expects candidates to embed concrete SLAs (e.g., 30 ms for notifications) in every design.

What compensation can I expect if I land an E3 role after passing the system design round?
Typical offers in the June 2026 cycle were $185,000 base, $30,000 sign‑on, and 0.04 % equity, plus a $5,000 relocation stipend. The package reflects the seniority of the role and the market rate for new‑grad SWE positions at Meta.amazon.com/dp/B0GWWJQ2S3).
