Pros
BlackRock has a great brand name, being the largest asset manager in the world with a massive margin (the second biggest is about half its size in AUM). Offers amazing flexibility to work on different areas and cross-team collaboration is encouraged strongly. BlackRock has a futuristic orientation and it lays great emphasis on the use and knowledge of new technology even for people who are working in finance roles. Work from home is not frowned upon and people are allowed to work from different locations if they need to do so for personal reasons. The quality of work for finance professionals is entirely dependent on the task that has been given to them. Some, who are lucky, may get to do great work. But as with all organisations, most people work on average quality projects. The global organization and the main asset management business is an amazingly great place to work. The global senior management is energetic, enthusiastic and inspiring.
Cons
HR practices are amateurish with no standardization of either compensation or designation. The level at which one is hired has no correlation with the quality of work or compensation. Thus one may be hired at a senior level and be given only low end tasks and a low compensation. On the other hand one may be hired at a low designation but expected to execute complex tasks, and be paid adequately for it, but (s)he may discover that numerous people junior to him or her enjoy a senior designation.
