Pretty much non-existent, applied online, walked in the next day with my passport after receiving a phone call inviting me to interview, the manager checked I was eligible to work in the UK then offered me a starting date the next day.
It was fairly easy, for example they asked simple questions nothing that was too difficult. They made me feel comfortable during the interview and the interview took around 10 minutes
I applied online. The process took 2 months. I interviewed at ASDA (Belfast, Nordirland) in Jun 2024
Interview
Good. Friendly interview. Put at ease and informal chat really. Asked about current experience and reason for leaving previous job. Asked about availability during evenings and weekends and was very clear on hours and expectations
