The process took two months. The interview consists of several phases:

• CV and cover letter screening
• logic pre-test
• logic and statistics test with short exercises
• more complex logic exercises
• introductory and behavioral interview
• technical interview

The process is very long, but it is clearly specified from the beginning and they are still very accommodating with dates and times. The exercises and interviews require a substantial time investment, but I think it is useful for identifying truly interested candidates. The overall difficulty is quite high but nothing unreasonable. Regarding the interviews, I had a positive experience with both the HR and technical figures, who were very helpful and prepared for questions.
