I applied online. I interviewed at BlackRock (London, England) in Nov 2024
Interview
Had 2 30 minute interviews with a mix of behavioural and technical questions. If you pass you move to the next stage which is an additional 30 minute interview either the same day or next day.
There were 2X30 interviews for the first round. After two weeks, another 2x30 interviews for the final round + excel test+ written test. I would say most are situational/behav questions. Good luck!
