I applied online. Had a phone interview them they called me after a week for an assessment day. I had to help and interact with customers on the shop floor. It lasted 1 hr. I received a £10 gift card after. The next day I got a call offering me the job.

Simple and efficient - lasted around 30 minutes with typical strength based questions. This included how do you interact with customers, how do you handle difficult situations, and how do you bring your best self to work. You may even have a floor walk.
