For college students, an on-site group interview is likely, without any phone interviews. I was contacted a few days after submitting an online application and resume, for an on-site interview later that month. All the interviewees were college students, both undergraduate and graduate. Due to non-disclosure I cannot discuss questions, but it is already known that these group interviews split candidates into groups of 3, and allow them to each work on a portion of a problem. You are given a laptop, and a choice of languages, and several hours (roughly from 9:30am to 4:30pm) to provide the code for the solution. During that time there were several interviewers who took us aside to ask us how we were solving the problem, first as a group, then as individuals. This part was closer to a standard interview: discuss the problem, things you fix, things you fail to fix, further work. There was a tour in the morning, and a Q&A with employees at the end of the day. Received an offer a few days later. Had 2 weeks to decide. Was given a choice of groups within the company to join.
