Pros
Good if you love travel, and lots of (non-monetary) praise for good work. Hired lots of trainees with no experience, so it would be a good entry-level job if necessary.
Cons
You are on the road 4 days a week ~45 weeks a year, usually in the middle of nowhere. Pay is crummy at entry level and you are expected to put in as much overtime and weekends as necessary. You get reimbursed for travel expenses a few weeks later. You don't really learn much; senior management has a "cookbook" and you just follow directions. Promotion to junior management is fast but based mainly on selling more work to your current client; promotion from junior management to middle manager is glacially slow. They had massive layoffs when the subprime crisis tanked their business.
