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.
