A recruiter contacted me via email a couple of times asking to set up a phone interview. The phone interview was about 30 minutes and they asked basic questions to learn more about myself and tell me about the job. Afterwards, I was asked to take an assessment within 72 hours. This included a lot of situation based questions and lasted about an hour. They contacted me via email a few days later asking me for an on-site interview in Detroit, Michigan. I had to decline because it was too short of notice and I am in college (they emailed me on a Tuesday and wanted me there by Friday morning but I had a midterm that day). I asked them if I could reschedule and they sent me an interview confirmation for that next Thursday in Cleveland, Ohio. The on-site interview was in a conference building and lasted about 2 hours. There was a 2-on-1 interview, a case study, and a math flow problem. They give you a sample math flow problem to practice before the interview but don't give you the case study in advance. I, personally, thought it was a very smooth process and the interview wasn't too bad at all. I didn't get the math flow problem right the first time but I still got an offer. I heard back 6 days after the interview (including a weekend) and they say you typically hear back whether you get an offer or not in 5-7 business days.
