Filled out application online, received an email a few days later asking to setup a phone interview. Phone interview went well, asked basic questions regarding what I knew of Groupon, what I currently do and told me a bit about the job. Scheduled a in person meeting where I met with 2 different managers who asked similar questions 'Why Groupon?' and 'Why Sales' were two common questions.
I felt the interview went pretty well but I was not contacted again. I followed up 1.5 weeks or so later and was told they were moving on with other candidates.
