Pros
Fidelity Investments is a great place to start your career. I started right out of college 2 years ago and the starting salaries are competitive. Plus, you get amazing benefits such as dollar for dollar match on 401K up to 7%. In addition they give you 10% of your salary for profit sharing at the end of the year. I have worked with a lot of very intelligent people that challenge me everyday to make me better. I enjoy the challenge because if we aren't helping each other improve and to learn new things a job can get stale very quickly.
Cons
While the salaries are competitive at the beginning the raises are almost none existent. And, to get a promotion is even more difficult. If your looking for somewhere to grow quickly then Fidelity isn't the place for you unless your lucky. Also, there is a lot of politics involved in this company. You will see coworkers move past you that are terrible at their jobs (borderline clueless as to what is going on), but network very well and talk to the right people. This can be very discouraging to those who actually try and work hard. Because, at the end of the day your picking up their slack and they're reaping the benefits.
