The process took 1 day. I interviewed at Zara in May 2011
Interview
Filled out an application in the store and received a phone call the very next day. The interviewer asked me about previous retail experiences or other experiences that I think would prove to be useful at ZARA. She asked me what I knew about the company and what I have to offer, etc. She told me about the fast paced environment and sometimes hectic hours and asked if I would be able to handle everything. The interviewer isn't trying to scare you, she is simply stating the facts. You are on your feet all day and this job will literally "keep you on your toes." You have to be good at multitasking and handling stressful situations because there is a LOT to do.
I applied in-person. The process took 1 day. I interviewed at Zara (San Francisco, CA) in Jun 2012
Interview
I applied by filling in an application at the store. A week later I got a phone call from the manager for an interview. I came wearing all black because their associates usually dress in blacks. The manager was very friendly and took me into her kind of office, I'm not sure if it was her office. She asked basic stuff like previous jobs and expected salary and hours. She talked a lot so I didn't have to do much talking.
