After submitting an application I was contacted by a campus recruiter and we set up a phone interview, which was pleasant. A few weeks later I got a generic email saying they were moving forward with other applicants, which was fine, but then I was contacted over a month later by a recruiter who provided the worst experience I've ever had with an interview process. She sent an email asking if I had time to talk with her about the sales internship in Boston, so after informing her I'd already heard back she proceeded anyway. I prepared for the phone interview, but 15 minutes after the scheduled time had passed I left her a voicemail and sent an email saying when I was free if another time worked better for her. I got a call back well after I had left the quiet interview space, at which time she seemed annoyed and claimed she had called me. She asked which internship I was interested in and was generally unprepared, and the call kept cutting in and out because her line was bad. The cherry on top was when that night at 7:30pm my phone rang. It was the recruiter, thinking she was calling a friend, and when I said who I was she responded with a laugh and a quick "sorry, wrong number!" Truly the most unprofessional and strange interview I've ever had, and I would never want to work with that recruiter again.

Straight forward - make sure to be yourself! There is an initial interview where a recruiter calls you back following your submission, then the hiring manager interview, then the senior manager interview.
