Avantages
During my time at the company (which was a little over 3 years), I found it relatively easy to earn a bi-weekly bonus. This job isn't for everybody, clearly - but since I'm not a career-driven person, it was a good fit for me. I came in, did my job, and left, giving no thought to the office until I returned after the weekend, which I think is the best way to approach this company. It's a job, not a career.
Inconvénients
A bit soul-sucking and very boring, tedious, repetitive work. The environment is cubicles with fluorescent lighting, and I found it very difficult to make connections- it doesn't seem like a unified team. Managers usually left me alone to do my work, but I know they didn't actually care about me (they were not aware that it was my last day, although I had related this information a month before and supplied written notice), and I hated the smug ranks of upper-management. It's my understanding that this company has downsized dramatically, cutting more than 3/4ths of their work force, and it was mainly a popularity contest when determining who would stay employed.
