Pros
There are a lot of friendly, smart, and interesting co-workers. They have a number of brand name clients. You had a lot of freedom and independence in going about your work, and initiating changes in the company. I think they treat workers reasonably fairly and straightforwardly. There is luck involved in how well your job goes based on the projects you are on. It didn't work out so great for me, but others had a much better experience. While people grumble about pay, I thought 50k right out of college was plenty.
Cons
I struggled to get staffed on projects. I came to the company straight out of college and didn't have most of the skills needed for particular projects. It got lonely working on things from home, and felt pretty disconnected from the rest of the company. There is practically no training program, nearly all the other employees were experienced hires from other firms. It could be a great company for someone else, but I needed more structure and support. I need to find a job where I go to an office and interact with coworkers face to face daily. They let me go after I wasn't staffed on billable work a high enough proportion of the time.
