I applied online. I interviewed at Gymshark (Birmingham, England) in Dec 2020
Interview
Only made it to the first round. The first round was an online "film yourself answering questions" format. Easy enough questions, but there is a time limit of 2 minutes per question which throws you off. Only thing I did not like is that they automate their recruitment process, you do not speak to a living soul before your interview (and even during, obviously). No personal human touch.
