Very torough interview, a series of brainteasers/logic problems that I had around 15 minutes to think about, then some problems I had to solve, and then discussions about workflows, etc. The whole interview took somewhere around 3-4 hours.

You first need to do a coding contest which is 4 hours and you have to solve enough tasks in the time limit to have an interview. The interview itself was pleasant, in general it was some small talk and talking about my university experiences. The interviewer always replied very quick to my emails and made the process go great.
