The interview process was fast and casual, they will most likely ask you basic questions. Don't expect that the time of interview will be followed, most likely you'll have to wait for hours and they don't notify you about additional tests & interviews that you'll have to take. After initial tests you'll undergo an interview and then another technical interview, the interviewers are from different departments and it seems like they don't have communication at all, they will let you wait for a few hours only to find out that your interviewer is on a leave of absence and you'll have to do it some other time.
