I regret wasting my time and energy on this process especially doing this during the December festive season. Mistake.
They require candidates to complete a lengthy case study that can take several hours to finish; mine was just under 20 pages. I understand the case study relevance but the interview process is too long and felt so repetitive. After submission of the case study and passing, you have to go through 3 interviews, each one focusing ONLY ON THE CASE STUDY.
They barely ask you anything about your experience, skills, or things like your vision as a manager. NOTHING. No one is interested in things like how you handle relevant matters like WFH, managing remote teams etc, a flaw in the hiring process especially for a managerial position.
It had been explicitly mentioned that there would be 3 interview stages, the last one being with the C-suite. They casually slid in a 3rd interview, meaning I'd have had 4 total if I'd gone through. The 3rd one was weirdly irrelevant since it was with someone from a completely different department and I'd already passed the line manager stage.
I then got a very quick rejection email after this ad-hoc interview. The vague reason for my rejection could have been easily identified in the first stage to save a lot of time. It seems they have their own set of rigid rules not looking for any diversity or creativity.
Case study, case study.
As said here and on Reddit and Blind, I would highly advise anyone, if you value your own time and wellbeing, not to invest at all in them.
The only positive thing I got is that I got prompt and professional feedback at all stages, which is rare for most as mentioned by others here who have even been ghosted.
Case study, case study. BIG WHOOP.
