from the interviews.

Real interviews, not guesses
Every question and the canonical answer is reconstructed from real candidate reports — interviewer style, the probes they escalate with, common mistakes, and outcomes. Verbatim quotes you can trust, 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 verbatim candidate quotes — 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 real question, 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 the verbatim candidate quotes that reported it.

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.
