Prep
Practice interview questions across six formats — conceptual, DSA, system design, behavioral, code review, and project deep-dive. Self-graded against a model answer and concrete signals. Pick a mock round below or browse the bank for free study.
Mock rounds
Timed, simulated interview rounds. Self-graded at the end.
One of each — the kind of round you'd see in a screening loop.
Eight fast questions on fundamentals.
Four problems with code + complexity walkthroughs.
One large prompt — 45 minutes of design + tradeoffs.
Six behavioral prompts — the follow-up drill, not a script.
Five buggy snippets — find it, explain it, fix it.
Walk through a project you built — architecture, decisions, tradeoffs.
