Amazon Lab126 Thermal Engineer interview questions

phone interview with hr, and then team member, after that, an onsite interview. The onsite interview has a lot of behavior questions, which the hr stressed in his email. Met two Indian guys during the onsite interview, both are barely decent person. One is a manager from mechanical design team, one is a member from that mechanical design team. The manager seems very sleepy, and he cannot keep his eyes open during the whole interview course. The other guy is the worst people I ever met. He tried hard to pretend he knew thermal, and asked a lot of foolish questions. And his attitude was very confrontational. After him, I interviewed the hr person, and expressed my concerns. But I guess that cannot help with anything.

A recruiter contacted me through Linkedin and requested a interview. I was schedule for a 45 min phone call interview with a manager. They called me on time and that was it.
