I applied through a recruiter. The process took 1+ week. I interviewed at Revolut (Londres, Inglaterra) in Dec 2018
Interview
tl;dr: genuinely nice experience. Can highly recommend.
The whole process took around 1.5 weeks,. It kicks off with a brief call with a recruiter. Second step, was a home assignment - I'd say it's standard difficulty. You get 3 days to complete it, which is not ideal on a busy week if you don't hit a weekend date. It's doable in one evening tho. Last stage were two tech interviews, 1 hour each. There was a small live coding exercise, but the atmosphere during the interviews was pretty chill, more of friendly conversation than a strict interview.
Interview questions [1]
Question 1
Some standard python stuff, bit of data structures, some high-level technology questions.
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.
