Tough - 9 stages of interviews from juniors to seniors. Questions on markets, technicals, fit, motivation and everything else. Follow-up interviews with the head of the team and a process which had continued to whittle down the number of people in the process until there was only 3 in the final round.

It was a one way interview on HireVue where I had been asked only 3 questions, each question being 3 minutes long and having the ability to retry one more time
