I had never had a group interview before so was slightly nervous, however there is no need to be, the interviewer was very friendly and overall the interview process was easy and relaxed. I would definitely recommend to do research as this helped me a lot. There were only 4 of us and were split into two groups. First we were asked to tell them about ourselves (mentioned previous work experience), then we were asked what we knew about the company, what is upselling and when we provided/received good customer service. After that we were required to do a role play in our groups where one person would be the customer searching for an outfit and the other would be a sales advisor, then we would switch roles. I found this role play simpler as we were not presenting it in front of others (would have been very nervous), however it was just a simple chat with the other person and the interviewer would just listen in on both groups. I had the interview on a Thursday and received a phone call the next day saying I was successful.
