The process was very smooth and pleasant. I was always getting responses and feedback within a couple of days after an interview (sometimes the same day), and I knew what to expect next.

The interviewers were very nice and helpful; I enjoyed speaking with them. It was definitely one of the nicest application experiences I've had so far.

I won't disclose the questions, but there were five rounds:

1. An online coding test (less focus on algorithmics than in other companies, but code quality matters). I had 48 hours to complete it.
2. HR interview.
3. Technical interview (programming languages/systems questions, data structures).
4. Final round (consisted of three interviews: one on algorithmics/maths, one describing in detail a project I've done in the past, and one 'systems interview').
