Vantaggi
BlackRock is a good name to have on your resume. The company is great if you don't want to have to adhere to processes, because they don't have them.
Svantaggi
But that's OK, it's also a fine place to work if you don't mind being treated like a simpleton. Having been a long time BGI person, and having been sucked into the BlackRock void has given me new perspective on my longevity with the company. Which is zilch. What the company wants now is cogs, not thinkers. My job was more like an old line from a pizza commercial which comes to mind, "Oh boy, I'm helping now, go to the fridge, get the cheese." Management wants all the control, all the decisions, and all the thoughts to be theirs, and nobody else's. They don't get the concept of thinking out of the box. They are in the box, and know every inch of that box.
