I signed up for an interview through my university. It was a fair interview, pretty comfortable. They are trying to see if you are driven and hard working. I got selected for a second and third interview at a later date which was a similar format. It wasn't difficult, they don't expect you to be perfect. They just want to see the potential and passion.

Several rounds of interviews meeting various team members. It was a fairly lengthy process that took about a week and a half. Everyone on the team seemed very nice and personable and truly wanted to make sure that they found a good fit.
