Frequently Asked Questions
Everything you need to know about our question database
We collect questions through multiple channels: tracking and monitoring sources where candidates report their interview experiences, working directly with engineers who have gone through these interviews, and our bounty program where engineers can submit questions they encountered and get paid for verified contributions. Questions that haven't been reported for over a year are archived, so you don't waste valuable time studying questions that are no longer being asked.
A valid question typically has multiple independent reports from different candidates. We cross-reference these reports to verify accuracy and ensure you're studying questions that are actually being asked in interviews.
We maintain a very high bar for quality. For each company we cover, we aim to be as complete, accurate, and helpful as possible, and we only add a company when a curated list is actually useful for focused prep. Some companies we intentionally skip: either their questions vary heavily by team or org, or the bank is so large (hundreds of questions) that a shortlist wouldn't help you prepare. Today that includes Meta and Apple. We're actively expanding coverage for companies where a focused, high-quality bank makes sense, but we won't compromise our standards to get there.
