3-stage process:

• HR Screen
• Code pair test with 2 engineers. Fairly enjoyable test as the engineers were friendly and engaged, and the test itself was pretty straightforward.
• Final stage: a 2-hour interview with the tech team to discuss previous work experience and technology used, followed by a call with HR to discuss more generic HR topics.

I was then ghosted after putting hours into this process. The BlackRock recruitment team was appalling, basically not replying to emails for clarification at any point and not explaining how to prepare for interviews – just "show up at this time."

Be careful with these guys. After so much time invested in the process, I would have expected feedback.
