I applied online. The process took 2 months.

The whole process consisted of several steps. At first, my profile had to be selected based on my CV and my cover letter, of which the latter was optional. After that, I had to complete a set of problem-solving tasks requiring only logic and basic knowledge of mathematics and probability. Some interviews with the hiring team followed, both behavioral and with additional problem-solving questions. The whole process took about two months. The recruiter with whom I was in contact always tried to keep in touch with me, providing me with updates and feedback. Overall, it was a nice experience and definitely worth the time and effort.

I can't disclose the questions because I signed an NDA.
