Discover interview questions

Applied through career fair. They contacted me after a week. Two round of back to back interview. First technical -- asked about past experience and questions on big data. Second HR -- routine behavioral questions.

I had 2 interviews on my university campus. One was behavioral, the other was a case. Both were very laid back. About a month later I was called in for an interview on their campus in Riverwoods. There were 3 behavioral interviews, a group interview, and a group case.
