I applied online. The process took 1 day. I interviewed at Subway (Truro, England) in Jul 2015
Interview
The interview went quite well. It was held upstairs in one of their booths and was quite noisy.
Also, the buses was late so I rang up ahead to say I might be late (luckily I wasn't).
Make sure to have a printed copy of the CV to hand in.
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.
