Candidate-reported interview questions from frontier AI labs and top tech companies
AceOffer reconstructs interview loops at the frontier AI labs from real candidate reports — every round, the reported questions, how a great answer goes, and the follow-ups the interviewer escalates with.
Browse free — the full Waymo, Mercor, Perplexity and Cursor catalogs plus 50 full-content previews, including sample online assessment questions. No sign-up needed to look around.
An AI interviewer that probes the follow-ups you’ll actually get
The same reconstructed rounds as the catalog — a reported question and the follow-ups candidates reported. Join the waitlist to get in first.
Share what they’re really asking.
Use any pseudonym. Compare notes with candidates who just walked out of an Anthropic, OpenAI, xAI, or Waymo loop.
No real name. No phone number. Just signal.
Candidate reports, not guesses
Every question and the canonical answer is reconstructed from candidate reports — interviewer style, the probes they escalate with, common mistakes, and outcomes. Cross-checked across reports, not scraped guesses.
Breakdowns built for the senior bar
Each question ships with the follow-ups the interviewer probes with, common mistakes, what passers actually do, and what candidates said about it — not a one-paragraph summary.
The whole loop, one place
Round formats, question banks, scoring rubrics, system-design breakdowns, and MLE deep-dives for a specific company's process — not a generic LeetCode pile.
See what “depth” means
One question from the catalog, the way AceOffer shows it. This is a single card — every question has this much.
Web Crawler
Given a seed URL and a helper that returns all links on a page, crawl every page within the same hostname, dedupe visited URLs, and strip fragments. Start single-threaded, then make it concurrent.
“How do you make the crawler concurrent without re-visiting URLs or losing the dedup guarantee?”
▸How a great answer goes
Working concurrent crawler, correct dedup under contention, and a clear explanation of the visited-set race — articulated, not stumbled into. Plus what the candidates who reported it said.

Interview questions go stale. Ours don’t.
Every month we fold in fresh candidate reports, so what you practice matches what’s actually being asked right now — first-party data competitors can’t scrape.
