Interviews were individual, but I had two interviewers, one was mostly just taking notes. This was a small Argos branch though. It was still a nice personable interview, although they ask a lot of questions. It lasted about 20 mins.

Received a phone call inviting me to an interview at Argos as they had my details from applying online previously. Sat in a circle with around 10-12 people, most around my age (17). Had to do a brief icebreaker telling the group what you learned about another person you were paired up with after a short tour of the stockroom. Then the interviewer split us up and asked our smaller groups to make a version of the store using cards and present to the others why it was designed that way. After this we were given a pen and asked to "sell it" to the group which didn't go well as I'm not the best at being put on the spot. It was more informal than I'd expected, I do understand that group interviews have to assess a variety of skills but the way it was done wasn't right for me.
