First stage was a written application. Second stage was four questions you had to answer in one minute via a video. You got a practice question but for the real questions you couldn't re-submit your answers. Third stage was a three-hour assessment day which was virtual because of covid-19. There were about 40 of us that day (there'd been another assessment day which I assume also had around 40 people). Half of the assessment was a case study which was fairly simple and the other half was three quick-fire interviews, each lasting about 15 mins. It was well organised and I enjoyed it overall, but my only criticism was that one of my interviewers didn't listen to anything I said, so much so that she asked the same question to me twice. She left a whole ten minutes for me to ask her questions. I know it was a long day and she'd interviewed lots of people and like everyone else she was working from home and she had a child jumping around in the background, but it felt very unprofessional. I'd been impressed by the first couple of stages of the interview process because of the quick responses. However, despite saying they would reply by the first week of December during the assessment, they never replied even after I followed up with them, which was very disappointing. I assume I didn't get to the fourth stage after having read Glassdoor reviews of other people who attended the same assessment day as me.
