I applied online. The process took 6 days. I interviewed at Tesco (Glasgow, Scotland) in Apr 2014
Interview
Very comfortable, but still formal. Mine was done with two other people - we were interviewed separately but shown the store together. Dressed smart and should remain professional throughout.
Completed a fairly short interview with two existing staff members (including manager) and then headed downstairs to do a trial shift to check how you performed on the checkouts and interacted with customers.
Interview questions [1]
Question 1
Describe a time you have helped a customer or client.
It was simple, basically why do you want to join Tesco and some soft skill questions. Tell me about a time you worked in a group, try to answer in STAR format.
It was done by a manager in a back room. It was formal and it was about 20 minutes asking about experience, peoples skills etc. this might have changed as this was like 6 years ago now
