Pros
Tons of Opportunities to grow. let me first say this is not a company that will hold your hand as your go through the process of building your career, but everything is there for the taking. There are tons of smart people and lots of resources, a large variety of work, and opportunities to even travel like crazy if that is your thing. If you can take responsibility for your own career then this is a perfect environment to help you grow or to set you up working with the top people and clients. There is a place for everyone in terms of company culture and outside of work life. If you like to party there's a strong party scene, even if you like to kick back or have a quiet evening there are opportunities. I personally tried out both, I found a deal of encouragement, brotherhood, and friendship working at IOA.
Cons
There are a lot of strong personalities and different structures within IOA that initially seemed a bit unstructured. However, I quickly realized sitting around and doing nothing got me no where, reaching out, connecting and asking for things got me everywhere.
