I applied in-person. The process took 1 day. I interviewed at Subway (Edinburgh, Scotland) in Feb 2020
Interview
The questions were about previous experience with food and food safety and hygiene and customer experience and handling difficult customers and handling difficult situations. The interview was offered based on handing in my cv in store and then had a chat with the manager the same day and was offered a job at the end of the conversation.
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.
