Interview
Phone interview first. Someone from HR called me and asked me questions regarding my experience, commute, and education. They interview was really quick and the salary wasn't great when I asked about the salary. Overall, I wouldn't like to work hard and on commission. This wasn't the right choice for me since I would like a higher base pay.

Interview
Interviews with hiring managers. Not that tricky. General questions asked on previous experience and motivations to work in Groupon. Managers were friendly. They're really just assessing your character and whether you're a culture fit.

Interview
Straight forward 30 minute interviews were pretty painless. Typical behavioral interview. Phone interview with HR and then 4 or so 1:1 interviews in person. Felt I got a good sense of the job during the interviews.
