Three stages, with a presentation - took quite a long time all in all. Nice people with an informal interview. Criticisms would be that there was more of a focus on selling the company to me than there was on learning more about me and my experience. After a three-stage process, plus an extensive task, I was sent a blanket rejection email. No phone call and no real reasoning for the rejection. HR team said that at this final stage, none of the candidates progressed.
