The guy asked a lot of mental math and brainteasers. For the mental math, he had me answer as fast as possible, and afterwards they ask you to bet on your answers. Brainteasers weren't too difficult, just make sure you think out loud. This one was first round on campus, and there will be more phone interviews and an on-site interview.

Initial application and online assessment. Had a first round behavioral interview where they asked me about myself, my experiences, and a couple of brain teasers. The interviewer was very nice.
