Pros
Great work life balance, ability to work from home when needed - flexibility when you are on the road. Many times you will be allotted free days of PTO if you have been overloaded with work or have been traveling. Good experience learning project management skills, working with well known fortune 500 companies - looks good on a resume. You have the opportunity to work on a variety of different projects and are given a say-so on what you work on.
Cons
The staff is horribly under paid considering the amount of work you put in. The "bonuses" and "raises" are essentially non-existent. There are people on staff who have worked for the company 10+ years and have only gotten pay raises 2-3 times. There are a lot of politics that come into play when it comes to who is promoted, it's not necessarily based off performance. It's almost not worth it to get promoted because you will get 5X the work with a VERY minimal pay increase. There's not a lot of room to grow with the company.
