Pros
Excellent Training Opportunities. I worked in both Sales Practice and Market Regulation and you got good exposure to broker-dealer regulatory issues. Internal movement is possible if you look into positions within the company and are willing to work in NYC or Rockville.
Cons
Absolutely horrific compensation. The worst in the industry and seems to be getting worse each year. Limited growth opportunities and the longer you stay, the harder it is to leave as FINRA's reputation outside the industry is spotty at best. This is a job for someone under the age of 30 who commits 3 years and moves on. Do not stay past 3 years!!! Terrible management as they are a bunch of FINRA lifers who only got promoted because they hung around and are willing to be donkeys for senior management. FINRA also has a tendency to hire people that nobody else wants so you will be working with some weirdos during your time there.
