Very conversational. For the few typical interview questions they did ask, they liked them answered in the STAR format S - Situation (context) , T - Task you were given, A -Action that you took, R - Result of what you did

I talked to the recruiters at the engineering specific and actual career fair at my university. On of them, and alum, interviewed the day after for 30 minutes; it was very casual, in which he just asked me questions about myself and also asked me to elaborate on certain details of my resume. Got an offer a few days later.
