Frequently Asked Questions
Everything you need to know about our question database
We actively track and monitor all sources where candidates report their interview experiences and questions. We also work directly with engineers who have gone through these interviews to capture the details accurately. 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. While we're actively working to add more companies, we won't compromise our standards. For each company we cover, we aim to be as complete, accurate, and helpful as possible. We ask ourselves: if we were the ones interviewing at these companies, would this service actually help us succeed?
