Pros
Salary and benefits are excellent. As long as you're billable, you have a relatively easy day-to-day job. There are friendly co-workers.
Cons
Company policies toward working from home and tuition reimburesement are quite good, but approvals can be nearly impossible to get even though it's theoretically a workplace benefit. There is no support for workplace skills development - you have what you had when you started the job (good luck getting training approved, especially if it involves a cost and/or travel). There is no useful communication from management, and the company randomly reorganizes on a quarterly basis. There is some amount of "work hoarding" among employees, given that billable targets increase each year to meet company financial targets, and this leads to "factions" (cliques) among work groups. It can be quite difficult, or nearly impossible, to get engaged in work that matches your skills and interests.
