The process of this interview was absolutely exhausting and not required. It started at 9am, had group tests and discussions and activities all day, I did not leave until 6pm, and additionally was left by myself for 2 hours in a room while they interviewed other candidates. I've been in management for 15 years and never have I been through such a process. I was then interviewed last, after 8 hours, totally exhausted and this is not a suitable environment for a stressful interview.
