Long with many rounds of interviews along with multiple phone calls. It was a comprehensive interview but mostly questions from the intervuewers side and not for the interviewee side. I would still highly recommend this company.

I met with them at my university's career fair. About two months later, I received a call that they want me to come to their office to interview and meet some people. Since I live 9 hours away from the office, I requested a phone/skype interview instead which they had no problem rearranging. The interview took no longer than 20 minutes and they didn't ask any questions. It was more to get to know me better and he almost was telling me I got the job. A day later, I received the offer letter

Pretty simple and easy. Spoke with two project engineers at a university career fair and was contacted to set up an interview. Attended interview with two project engineers in field office haven't received an offer yet.
