Mercer Phoenix has a strategy of finding intelligent workers and then pitting them all against one-another in sort of a "may the best man win" sort of way.
After I had been there for about two months, a colleague told me that in order to be successful there, you needed to be able to throw other people under the bus, and in his mind, I didn't have what it takes. He was a major under-the-bus-thrower and is very successful there. The bullying culture was unlike anything I have seen in my career and not something I wanted to get used to.
