The first interview is a phone interview using the STAR format and then a onsite interview. It was about a 2 week process. After the onsite interview I received an offer by phone a week later. I then reviewed offer with recruiter and went over any questions that I had. After the contract is signed then you have a drug screen and background check (about another 2 weeks process). After the results come back then you get an orientation date.

I met with two HR people, no one else. Interview was pretty straight forward and easy. I didn't know which group I was interviewing for, just that I was interviewing for a general engineering pool. HR interviewers were very friendly and pleasure to speak with.
