I had 2 interviews back to back of 30 minutes each. One was purely a coding round(2 questions) and another one was based on a resume, OOPs etc. In both interviews, there were 2 software developers.

I visited with Groupon at my school's career fair, and then was able to land an interview for the next day. The interview was technical and about an hour long. After waiting around a month for a response, I heard back from them for a follow up interview, which would be the final round. That was an online interview with three rounds in three hours. Two of the rounds were technical and the other was a behavioral.

The interview process was great! Amazing people. I first had an interview on campus the day after I met them at the career fair. The interviewer was very friendly and made me feel comfortable. The questions were medium level Leet code. I could solve 2 of them but struggled a bit solving the third one but she helped me out. Within a week, they got back asking for my availability for 3 hrs back to back online interviews. The first was an HR interview which went well. The second was a design round. Third was technical-Some java questions, algo. Overall a wonderful experience. They got back to me with results after two days.
