Revolut HR Manager interview questions

Rather odd experience actually. An online quiz / test. Some fairly innocuous questions around attitude etc. Interspersed with a few utterly pointless (and easily googled) maths questions. If you run round a track at x mph etc. I'm in my 50s. Who cares! Then I had an interview with an HR bloke who was a bit dismissive. He said the process could be another 4 or 5 interviews of a pass / fail nature. Really? If that is how they operate at interviews, what must it be like working there. No offer made and I would have rejected it anyway. Come on folks...you don't need that many hurdles for a candidate to get through. It's amateur hour.
