I applied online. The process took 1+ week. I interviewed at H&M (Manchester, England) in July 2016
Interview
Telephone interview with basic customer service questions, then invited to a group interview with around 18 other people but then we got split into 3 groups of 6. Really easy just did group activities. A few hours later I got a phone call inviting me to a 1:1 interview with the manager which was really informal and went really well. 2 days later I received a phone call with the induction and job offer :) just research h&m as a brand and have basic customer service questions ready to answer.
group interview, people were friendly and they asked a lot of general questions. then we all went to the shop floor, got assigned a certain outfit to make for a hypothetical customer and explained in front of the group why we chose it
I applied online, interview at the store. Casual talk with the store manager about the experiences and how the store works. It was pretty straight forward even without any experiences.
Group interview. 10 candidates in a small dingy room. Poorly organised and interviewers showed very little interest or skill in conducting an effective interview. Were in pairs for the whole thing, no way to stand out and other people taking credit for your ideas. No observation of how you handled planning and answering the tasks in your pairs, interviewers just sat there having a chat.
