Basic technical troubleshooting questions. Friendly interview process overall. Also product related questions I believe that the interview was done in 3 steps. First personal interview, then manager and technical interview and the final offer then if successful.

First interview - HR Second Interview - Managers Interviews were straight forward. Following HR's recommendations on study topics give you a guideline for the technical interview. Interview with managers is typically done with 3 people interviewing you. Possibly another person will join to give you your final evaluation or possibly another interview is needed.
