I went to the back of Greggs and did a 30 min interview with the store manager. They asked various questions which were all on an ipad. Make sure to bring proof of identification with you.

Very informal and very typical questions, I was markedly unprepared and still performed well. Very friendly interviewer as well. We met up for the interview and did some admin stuff (like sizing for uniform and ID checking) and then they contacted me the next day
