I applied online. The process took 2 weeks. I interviewed at Waitrose (London, England) in Jun 2020
Interview
Online assessment followed by one to one interview involving completing a written set of scenarios and going through the answers with the interviewer. Not too formal need to dress smartly for best chance.
Interview questions [1]
Question 1
Provide an occasion when you have shown perseverance
It was OK pretty standard. Questions included team building and one to one interview.
Everyone in the room good a job except one person who was clearly incapable of doing said job.
Standard interview with behavioural type questions. There was also a group interview where they focused on team building exercises. It was quite easy. Everyone in the room got the job except one person.
