There were several interviews, couple by phone and one face to face. On face to face interview the people were friendly, the atmosphere was nice, there were no complicated questions, nor tests, few technical questions. First I talked with managers, describing my previous experience, etc. Then there was meeting with technical part. There I described my previous experience once more and they asked several technical questions. From my point of view I responded to everything (maybe not perfectly but I knew the answers). Few days after I clarified they changed requirements (or set of skills) required for this position. Don't know what it was, haven't faced such situations previously.

Extremely friendly, detail oriented process where there were multiple interviewers at the same time. Most likely interviewing with the team that you would be working with, from manager to lead.
