I applied through university. The process took 4 weeks. I interviewed at GHD (Worcester, MA) in Oct 2013
Interview
The interviewer came to my school to interview people for the day which had been advertised to students. He was very professional and knowledgeable about the subject. We had a casual conversation and he did not do or say anything to make me feel nervous. He also contacted me within a week to follow up on the interview which I thought was nice.
Interviews were all teams. Interviewer spent more time talking than asking me questions or listening to my answers. Each interview (there were 3) seemed like the one before and was with the same person.
