I applied online. The process took 2 weeks. I interviewed at Revolut (Dubai) in Jun 2024
Interview
First a phone screening with a Recruiter. Second was a live coding interview which was easy. The task was to implement a java program that simulates a URL shortener. I say "simulate" because you obviously don't have time, given the 60 minutes, to implement a full-blown url shortener. The objective here is not to be able to build a real URL shortener, but to be able write clean, maintainable, and tested code under pressure.
Interview questions [1]
Question 1
What does ACID stand for? Name the database isolation levels.
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

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.
