Design questions

Mid-level and senior candidates get one design round focused on APIs, idempotency, ledgers and reliability. Staff candidates also present a past project, and explaining its business impact poorly can lead to down-leveling.

Worth knowing

The signature rounds are Bug Bash (fix bugs in an unfamiliar codebase) and Integration (build against a real API from its docs).
Questions are written in-house; standard puzzle problems are rare, so practise parsing, ledgers and multi-part prompts.
L1–L3 are all 'Software Engineer'; L4+ is 'Staff'.
Sources disagree on AI policy: ask your recruiter.
