I went through a preliminary interview with an HR manager and it was mostly behavioral questions such as "tell me why you want to work for this company" "tell me about your past work experience" and so on. After i got accepted for the final round interview you meet with 5 managers and another HR manager and they mostly go through another round of behavioral questions. The whole interview process was pretty relaxed and as long as your values are in align with the company you should do fine.
