I applied in-person. The process took 1 week. I interviewed at Gap (Milpitas, CA) in July 2010
Interview
First, we submit an application in person which you can probably do online now. I applied for the Summer season. All of the candidates meet to have a huge group interview. We all sit in a circle and we introduce ourselves. The manager will ask some questions and you raise your answers to participate. Then they call you back and give you an offer.
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.
