The process took 1 day. I interviewed at Gap (Chicago, IL) in July 2010
Interview
It was pretty good. I learned a lot about the company. I didn't really want to work there though so I didn't get hired because I was not enthusiastic enough. Other than that, I have nothing but good things to say about the company
Group interview with other candidates with the store manager. Arrive at the store and wait for other candidates. Then interview happens in break room and it lasted roughly about 30-60minutes
It was a group interview of about 10-12 people. If I remember correctly they take you to the back, the stock room, and ask almost everyone the same question. The interview lasted about 30 minutes.
It was very easy, one in person interview with the general manager and then I was accepted! Mainly personality and behavioral questions were asked, and I think enthusiasm on my end helped the most.
