The process took 2 weeks. I interviewed at BlackRock (Princeton, NJ) in Apr 2012
Interview
Mostly resume and fit based. Asked lots of questions about why I wanted to work at BlackRock specifically. First interview was a 30 minute phone interview followed by a super day a couple weeks later. Overall, a pretty good interview experience.
Interview questions [1]
Question 1
Why do you want to work in Asset Management as opposed to some of the other divisions?
