I applied through university. The process took 2 days. I interviewed at Rolls-Royce (Indianapolis, IN) in Jan 2015
Interview
I got the interview through meeting a college recruiter on my campus. The next day I had an hour long phone interview. The college recruiter was friendly and the phone interviewer was very helpful in explaining some of the questions. The next step is to be invited to an assessment day for more interviews and some critical thinking / project tests.
