I applied through a staffing agency. The process took 4 days. I interviewed at Groupon (Chicago, IL) in Mar 2012
Interview
Casual interview process, They only care about sales experience. If are willing to come in early stay late, and get mildly compensated for it. Then this is the place. There will likely be two separate interviews with two separate people. A nice guy/gal and a tuff guy/gal.
I applied through an employee referral. I interviewed at Groupon
Interview
Phone call then an in-person interview. If you qualify through the phone call, they ask you to come in the next week. Business professional dress, usually meet with more than one person.
Interview questions [1]
Question 1
Why should we believe you are a motivated individual
Applied online on a Monday. They contacted me Tuesday for a phone interview which was Friday. Very basic resume questions. Had the inperson interview the following Thursday, got offered the job on Friday. Very laid back. I think most of the interview was me and my questions.
