Interviewed through a campus recruiting event. About a 45 minute one on one interview with recruiter. First gave a brief presentation of my research then discussed it. There wasn't enough time to go into details of research. Mostly standard behavioral questions after that- your working style, approaches to challenges, etc.

They were holding on-campus interviews. I submitted my resume online and was called for a one-to-one interview two days after submission. The interview lasted about 40 min but the person interviewing was snoozing right after I started answering his first question ("tell me a little bit about yourself"), even though the interview was at 3 pm. The employee tried to stay awake and take notes but clearly not the most appropriate person to bring as a recruiter.

A research summary was required before you go to next step and interview notice was sent by email. I was interviewed on campus a career fair. Got a few common behavior questions. The total time was about 1 hour. The interviewer was nice but it seemed he was tired after interviewing candidates all day.
