I applied through an employee referral. The process took two weeks.

I got contacted by a recruiter to apply on their website, and first they asked me for my CV, cover letter, and university grades, and then I did around six tests about behavior, programming, and discrete math/logic. Unfortunately, I wasn't accepted to the next step where I would be expected to attend some behavioral and technical interviews.

I signed an NDA, but what I can say is that it doesn't require you to be a genius in programming to solve the problems. You were even allowed to answer with pseudocode.
