First exchanged emails with a recruiter who I later had a phone interview with. One week later I was invited I site for a face to face I interview which consisted of meeting with 4 people for 45 minutes. It also included a math flow problem and a case study which was provided to me prior and then discussed in two of the interviews. Math flow was very easy and the case study questions are common sense stuff. It was a little nerve racking meeting, but my interviewers were incredibly friendly and easy to talk to. I enjoyed hearing about their experience a within the company and they seemed genuinely interested in what I had to say. Overall it really was an enjoyable experience.
