Applied Materials interview questions

3 interviews, the first 2 with head teams, the third with group manager. mostly about past experience and projects (even though its a graduate role). asked a few logic questions

Interview was an hour in two stages, first half went great, talked about myself, previous positions. Second half was technical, and the interviewers had nothing prepared, didnt ask any technical questions, and spent the entire time trying to prove haw smart they were. They were not convincing.
