I applied through a recruiter. The process took 3 weeks.

This was my second time applying. I had:

• 1 machine coding round where they give you a half-baked app and ask you to complete it with follow-ups on concurrency questions.
• 1 system design round focused on mobile and a bit of BE as well.
• Team fit rounds.

I mostly had a positive experience, but my team fit rounds were not good. It looks like they were rejecting me for any reasons whatsoever. I got feedback like over-sharing, only communicates with BE and Data and not much with Product, and not convincing answers for why to join Revolut. I couldn't connect projects with business impact.

I had 3 team fit rounds overall. The last one was very horrible and, to be honest, very disrespectful. When I asked as a team/company culture how do you handle new joinees, I got an answer like you either start performing from day 1 or get fired. Also, I had researched some questions on the team and prepared some questions to ask them; their reply was I don't have to worry about it as I won't be working on that part of the team. Who answers like this? Complete unprofessionalism.

I do agree the last team fit I blundered a bit, but replying to my questions in this way shows what kind of culture they are brewing within the company. After the last team fit, I wouldn't apply again here. I prefer self-respect more than money.

Given a basic cache implementation, how would you handle concurrency?
