I applied online. I interviewed at H&M (London, England) in Sept 2017
Interview
Phone interview. Very quick round 10 minutes long. Basic questions and easy to answer on the spot. Was called back the same day to be offered a group interview a week later but didn't attend
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.
