It was a generic interview that took less than one hour. Started off with some "get to know you" questions and sharing experiences and projects while the interviewer explains what the program is about and the possible things you'll be working on Then, moved on to more technical questions which is mainly about your knowledge on feature X/Y/Z on a microprocessor and some trivial questions which you'll know if you have studied them, if not then not really entirely your fault since universities cannot teach everything. So just try your best, if you dont know just say dont know. It was around 30-40 min interview.
