I applied in-person. The process took 1+ week. I interviewed at Subway (Ascot, England) in Mar 2016
Interview
it took about 2 weeks, the interview was very quick and welcoming, the interviewer was very nice and the questions were simple and casual. Mostly about times in which I was available to work.
Interview questions [1]
Question 1
Have you ever had to deal with a difficult customer? How did you do deal with it?
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.
