Pros
Worked on a variety of projects and, thus, gained experience.
Kontras
All that matters is money. Everyone is constantly worried about being 100% billable which means working extra hours to get to know your colleagues or even go to lunch or a staff meeting, which is charged to "indirect" time. I personally worked at multiple client sites and at ICF headquarters making it very challenging to develop relationships at any one place. Everyone was always worried about being laid off! Speaking of, when colleagues were laid off, it was kept a secret and those not in mgmt would only find out because they'd eventually notice someone was missing!!! They seriously need a manual in best practices in leadership! The worst thing that ever happened was when I woke up with a migraine and requested the day off-my project manager requested that I come in when my pain med kicked in; I had to remind her that you're not supposed to drive. The request was absurd!
