I applied through another source.

During the selection process, I was asked to find solutions for two sets of four problems: a coding challenge, then a video interview, and a final onsite interview. The problems consisted of coding problems, where you have to provide a pseudocode implementing the strategy to return the correct solution, and math/logical problems, where you had to show the reasoning that led you to the solution. I would say that they were thought to test problem-solving skills rather than specific tech knowledge, so I would suggest not to worry if you don't remember how to implement a Fibonacci heap or similar. I found them quite challenging with respect to the ones of other interviews, and I also had a lot of fun. The video and the onsite interviews were more behavioral than technically based.

I was a bit nervous, especially during the onsite, although the atmosphere was quite relaxed and friendly. I enjoyed the whole interview process, and I appreciated that during the entire process, no strict time deadlines were imposed in any step, so one can try his best with no hurry. Last but not least, I would suggest practicing on HackerRank if you are new to a coding interview, just to gain some confidence on how to approach a coding problem.
