I applied in-person. The process took 2 days. I interviewed at Topshop (New York, NY) in Sept 2012
Interview
They tend to hold open interviews where you are able to come in with out an appointment. You should have a resume ready and be dressed either for a interview or fashionably in Topshop/ Topman merchandise. The 1st interview is quick and relatively simple. They just ask you three to five questions in regards to your work experience, about yourself and scheduling.
