Had to complete two separate aptitude tests as part of the online application. You're prompted with different scenarios and you have to choose which solutions are best suited to the each scenario. Fairly simple stuff -- just common sense really. Take your time though. They followed up my online application with a text message asking to come in for an interview. I had already looked at some of the recent interview reviews on Glassdoor, so I was expecting a group interview. There were 4 other applicants at the interview and we all sat down on one table. We were asked to come up with a guide for new selling assistants at John Lewis, which were: - 5 ways to deliver good customer service. - 5 ways to handle a customer who is upset or angry. - 3 ways to enhance product knowledge. I would suggest doing your research and come up with some solid points beforehand. Make yourself heard, but remember to listen and engage with other people in the group. I got the impression this was something they were looking at closely. The group interview was followed up with a 1-on-1 interview. There were 5 questions. The first was tell me about yourself; the others were customer service based. The last question was just reiterating what you had already contributed to the group. Overall, a really positive experience as it was quite challenging and rewarding in the end.
