Pros
The company is run by a small group of very, very smart people, with whom it is often a pleasure to work, and from whom you can learn a lot. When first working there, it felt as though my contribution would be understood, and could be part of this galaxy of success that they all seem to fly in. At times, that was the case. When things go well, they are the most appreciative and perceptive managers imaginable.
Cons
There are times when -- appallingly-- ego gets in the way, and management simply does not listen. I was shocked to find that I was thrown under the proverbial bus time and again by someone who didn't know what was going on, but needed desperately to be seen as someone in charge. Downright lies and misrepresentations were allowed to stand, and the communication that I thought was so good at first, suddenly shut down, and I was bounced rather unceremoniously. I felt they misused a number of people working there, and steamrollered over them because they could. I watched it go from a wonderful place to work, to an elite club.
