Second Round interview was very informal. Half interview, half was a case study.

I turned in my resume during an career fair at my university, and got an email back around 3 weeks later. The recruiters will reach out and hold info session, plus social lunch every week. They boast on their cultural which is very relaxed and family-like. They started with almost 130 people for interview and narrow it down to 12-13, so don't feel special when you got an interview request. They tried to interview as many people as possible. For a small company, the competition is surprisingly big. First round is behavioral, second round behavioral+case, third round is not technically an interview it's just a social dinner with senior management. Very standard questions. They mostly just want to see if they would like working with you or not, none of the questions I got had to do with any skills or qualifications, so try to be as likable as you can be because that's one of the main things they're looking for.
