I applied online. The process took 6 weeks. I interviewed at Revolut in Jun 2024
Interview
Five rounds, HR (with some basic technical questions), live coding, live coding + technical conversation, system design, team fit. The process was relatively straightforward with prompt feedback between rounds and information regarding what to expect in the next round from the recruiter.
Interview questions [5]
Question 1
Basic technical questions (time complexity of hashmap get, how to achieve concurrency, sharding vs replication etc)
Live coding exercise with focus on perfomance and concurrency and testing (bonus for using tdd). Three requirements, you only move to the next requirement if you complete the previous one.
Live coding exercise to implement money transfer between accounts, focus on perfomance and concurrency, discussion on how testing would be implemented. In-depth discussion about database transactions, indexing, query optimisation, isolation levels, optimistic/pessimistic locking, distributed transactions, stability patterns, ddd, etc
Why do you want to work for Revolut and what are you hoping to achieve in Revolut. Past experience, interesting and difficult task you've done and how you went about it.
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

Question 1
Concurrency
Optimistic vs pessimistic locking
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.

Design Revolut Stays. Hotel info comes from an external partner. Bookings must be done through the external partner as well.
