I got hired for the Enterprise Emerging Leaders Program straight out of college. The whole process took a little less than a month and was very straightforward. After I took the multiple skills assessment for the job, I got an email telling me which office locations I had been referred for. Soon after, I got contacted for a phone interview. There was only one interview after that, which was a panel interview. Interviewers were professional and nice. I would say the best way to prepare for the interview is to look up "performance based interview questions" and practice answering those.
