No behavior questions.
Technique questions mainly are what you have learned in school and they expect you to know Operating System, but if you don't know something, it's also fine since they will give you training, and they taught you the knowledge points that they asked but you didn't know. They also asked about Data Structures, preferred languages, Operating System, etc. Also, code and debug on the white board.
The interviewers are super nice, trying to help you a lot.
