I got the interview through backdoor. So, I only had one interview. It was pretty straight forward and the interviewers were nice and friendly. I had a panel of 3 interviewers interviewing me.

The process consisted of 3 interviews, the first two being by phone and the last being face-to-face. I was contacted a week after submitting an application for a phone interview with a recruiter at HR, who inquired about standard stuff and asked about my experiences. That information was then taken and further dissected with a second interview, this time with a Senior Software Engineer. I was then asked to come on-site for an interview with a panel of internship sponsors, asking mainly about my education as they appeared to be unfamiliar with my program. The process went surprisingly quick, and I was rather satisfied with it in general.
