First there was a Skype interview with HR. At the end she told me she will send me details for the next step - online test. The test is mostly about logical thinking, continuing patterns, calculating some percentages. Note though that you need to answer questions really quickly as it cuts you of (and continue with the next question) if you don't answer fast. The test lasts one hour and you have one week time-frame to do it.
After that there is an onsite interview. We had to do a home task for that (prepare a pitch). First there was a tour around the offices and then an interview with another HR with some typical HR questions (describe a time when you failed, when you worked under pressure...). After that there were 3 different parts - presentation of the home task (pitch), role play (negotiation skills) and case study (come up with a new product and describe it). For every part there were 2 product managers discussing with you.
The interview process was very pleasant, the HR is really trying to make the process nice. They telly you in advance how the process will go. They also tell you their feedback at the end and are always happy to hear how they could improve the process. You really get the feeling that you are not just a number, not one of thousands applicants, but they care about you.
