I applied in-person. The process took 1 week. I interviewed at Gap (City of London, England) in Sep 2011
Interview
The hiring process is generally three rounds, where first one is about telephonic interview. They ask you pretty generic questions, for me I thought they just called in to know if I spoke English well or not. Once that was done, they asked me to come to Gap for a Group discussion which is then succeeded by a 1:1 or sometimes 2:1 with manager(s).
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.
