The whole application process was very efficient and well organised - it took less than two weeks (from first interview till getting an offer). The first step was interview with HR with general questions, followed by an interview with the manager. The second interview was more challenging but really enjoyable (experience + logical questions). The third interview was a more technical one where I had to solve different cases on the go and walk the interviewers to the process (they were mainly interested to understand how you think. The last one was with a managing director and it was really interesting and also quite challenging (again a lot of logical questions).
