Pros
Formed some good relationships with co-workers. The pay was decent for the work we were doing. The relaxed dress code and flexible schedule were nice.
Cons
The managers didn't seem to have any real management training (not their fault, really), and were saddled with a ratio of 50:1 when dealing with people in their project groups. This meant that projects went largely unsupervised, and only people who sought out guidance received it beyond the very occasional email. The third-party client we were contracted to was generally disorganized and communicated poorly, so our guidelines were unclear. The client would also throw the occasional temper tantrum and pressure the managers to threaten all of us with termination if we didn't improve at something--so we would go from hearing next to nothing from our managers to hearing that we were all on the brink of losing our jobs without any warning. It made things...tense.
