I had a phone interview with a recruiter and then was invited to come in. A couple weeks later I came in and spoke with a recruiter, HR director, Sales manager, and another recruiter. It felt overall positive and I was complimented by the sales manager multiple times. And here's the weird part: I never heard back. At all. Multiple e-mails, checking their job site for my status (still pending), and nothing. Ever. Based on this alone, I would never apply for another job at Groupon. I think it is incredibly unprofessional to not let a candidate know one way or the other, especially for such a large company. Only in the last few weeks, 7 months later, my status was changed to declined (surely because they were just updating their database). Perhaps the billion dollars of funding will help them be on top of their hiring process.
