Consisted of two rounds:
1. Numerical and logical tests + interview with HR about your personality, interests ...
2. Interview with team members and a partner
Overall impression: All of the abovementioned interviewers were nice and approachable. For instance, the HR specialists assessed my skills and previous experiences and compared them to what was expected from the job. A piece of advice for anyone would be to be yourself. If you do not pass to the second round interviews this does not mean that you are not capable enough, but simply you would feel uncomfortable at this position according to the HR specialists.
