Four stages - submit CV, cover letter and a short paragraph. Then, automated video questions. Didn't hear back for two months then received a phone call inviting me to an interview with the talent intern and two current Gymshark analysts. Then, final interview which was a project task involved lots of data and preparing a presentation to last roughly 30 minutes. Presented to the same people as initial interview plus another data manager. Heard back quickly from both interviews. You had a week to prepare for the project task. They were all very friendly and made me feel very comfortable and asked fair and answerable questions whilst still challenging.
