Pros
The best reason to work for BlackRock would be job stability. They are not a hire and fire kind of a firm rather they believe in being understaffed. The average age of employees is lower compared to other firms. They hire from some of the top colleges. There are "some" brilliant people you feel proud to work with. The company believes in respect for everyone and the senior members are very communicative. The career opportunity is limited although they say that you can move around in the firm and do what you like. Pretty good at food and travel allowance
Cons
There is absolutely no work-life balance at this place. They are always understaffed and in a group like Portfolio Analytics you are looking at a 70-75 hours week. The compensation is low compared to the hours you put in. The work atleast in the first year is repetitive and gets monotonous. The firm seems to have passed on knowledge through the word of mouth. The systems/processes are not well documented. The attrition rate is high.
