Pros
It looks good on a resume... OR at least it did when I left. Being able to work at what appears to be a industry leader for a couple year and make contributions looks good for future employers.
Cons
Oh where to begin... 1. Senior Management live in their own world completely oblivious to what is going on in reality. They are completely disconnected from the "worker bees" who really make the magic happen. 2. You might be an expert in your field, but Senior Management DOES NOT CARE. They are the VP's so they know best in their opinion. Despite most having no formal training or experience in the field they are managing. 3. Continuing with the theme, the nepotistic nature of the company, means that if you know someone and suck up enough you might get promoted to a position you hardly deserve. That leaves the rest of us wondering on a daily basis why and how these decision are made. 4. You are expected to be perfect. If you make a small mistake you could be fired so that the senior management can make an example, or appear to be handling the situation. This leads to people working in constant fear, and lying when they do make mistakes to avoid being a target. The irony being that if someone at the lowest level makes a mistake, it can be traced to the very top, and the faults of the management being the ultimate culprit. 5. On the flip side from #4 Senior management can often make mistakes, some costing the company hundreds of thousands, if not millions of dollars, without any consequence. 6. Salaries are far from comparable. Needless to say if you work there or are considering, just look at how much the senior management makes below, and compare that to your salary (that should be a major clue for you): http://bit.ly/pmjWGI 7. I could go on, but you get the idea.
