I applied through a recruiter. The process took 2 weeks. I interviewed at Revolut in Dec 2024
Interview
Horrible interview. The interviewer didn't want to discuss anything or listen to what solution I was choosing and why. He only cared about the code. I decided not to write all the tests, but to discuss everything that I would test out loud, since 45 minutes is not enough to write several implementations and cover them with quality tests. In the end, I was rejected because I didn't cover the edge cases with tests. During the implementation, I optimized the solution from linear to constant complexity, but the interviewer decided in his feedback that by doing so, I simply complicated my code.
Very kind. The questions weren’t easy, but with knowledge of database configurations, concurrency, locks, and some practical experience, you are able to answer them clearly, confidently, and effectively overall. It was good time.
Recruiter round, they’re basically looking for buzz words. They asked for my experiences in handling different scenarios, then other db and concurrent related questions . Overall it was straightforward, just go through other’s experiences here and you should be covered

Db isolation levels
HR interview, coding interview, then system design interview. No specific feedback from them. I really thought I went well and answered everything at least reasonably, but didn't get an offer.
