I first did an on campus interview which was 30-45 minutes long. I was contacted again a few months later to do an onsite interview. I however had another offer with a short deadline (within 2 weeks) which is very short to do an onsite interview and hear results from but they were able to schedule the interview and get me results within that timeline which was awesome. During the onsite interview, I interviewed with 4-5 people each an hour long except for the lunch interview. The lunch interview was 2 hours long, one hour for lunch and conversation and the next hour for a coding interview. The rest of the interviews were also coding interviews. Everyone was very pleasant, interested in their work, and excited to talk with me. They also all seemed to love the company which left a great impression on me. Overall the interview process was very pleasant.
