Most of the individuals you have to deal with on a day to day basis on your team, or others you interact with on a daily basis are some of the worst people walking this planet. As mentioned above, they are some of the most egotistical, narcissistic, rude, unqualified individuals you will ever meet. Every client issue is a matter of life and death, and they will make you work day and night until the seemingly so important issue is resolved. And then once you do resolve the issue, you will get no thanks from them,they will just move onto the next "urgent" issue. They put the client first and not their employees, which makes for a very toxic environment. Not to mention, these individuals walk around acting as though they are working on the cure for cancer or something else super important.
There is no culture and the employee / manger relationship is non existent, you are just made to work as though its a sweatshop. There is no recognition for any work you do, or any of your achievements. The only reward you get is more work to be completed, and you will be called on the weekend if anything goes wrong.
There is a zero work life balance, look forward to being on call for about 24 hours a day, because half the people at the firm are barely competent enough to get dressed in the morning, let alone resolve any issues on their own. A normal workday is 8:30 AM - 8:00 PM, and expect to be hunted down if you are not in the office and someone happens to be looking for you.
Additionally, internal mobility is a complete joke!
In conclusion, you would have a better time in prison then you would working at BlackRock.
