I applied for a part time role while at sixth form. The interview was conducted as a group of about 10 of us.
We had to complete an online questionnaire before being invited to interview that was scenario based.
Lengthy process, four rounds to be a sales assistant. Had to sell a product to a group of people. Phone interview, group interview and one on one. Offer given really promptly. Good interview process.
I applied online. The process took 2 days. I interviewed at Waitrose (Trumpington, England) in Apr 2019
Interview
I had Face to face with few of the questions and had a group discussion, interview and some conflicts to solve based on our knowledge and experience. It took us 3 hours to finish all the process. They were really nice and helpful.
