I applied for the internship via LinkedIn. I received a call back the very next day to schedule a phone interview with someone from HR. The phone interview was straight forward. They started by asking what I knew about the company then some basic behavioral questions. They called on a Monday to schedule an interview for the next day (luckily I was home for spring break at the time). There were three half hour interviews at the headquarters all of which consisted of behavioral questions. I received a call back two weeks later with an offer.
