I applied online. The process took 2 weeks. I interviewed at Subway (El Paso, TX) in Feb 2013
Interview
It was a very easy and fast process, just like any other fast food place. I applied online and got called in for an interview the following week. Very basic, straightforward questions. I got called in a week later to work. Overall it is a very basic interviewing process just like any other fast food chain.
I interviewed at Subway (Barnsley, South West England, England)
Interview
I was sat down and asked questions about myself in a possible manner in the middle of the restaurant as people dined around me. I was then instructed to cut bread so they could see how well I could do.
Easy flow, face to face and they are quite patient with you. The manager are understanding if it's your first time and let you through the flow of the process
Very simple and straightforward. Normal questions like availability, have you worked in food service before, etc. I think it depends on location though since friends at other locations have had more substantive or less substantive interviews.
