Pros
I worked in transfer pricing at BDO USA, LLP. BDO is generally competitive with the Big 4 accounting firms in terms of salary and benefits, maybe slightly less. The office atmosphere was generally positive, and there are many good, intelligent people working for the company.
Cons
The leaders of the transfer pricing group are classic bullies. Soon after I began I was told that the guiding metaphor for the group was that one employee was always to be singled out as the "wounded wildebeest"--the employee that management, the keepers of this metaphor, wanted to hunt down and kill. They followed through on this approach to management: there was always one employee being targeted for dismissal, often based on purported underperformance that existed only in the minds of management. I was continually told that I was "too nice" to my subordinates because I refused to join in the predatory environment. I was also told that regardless of my actual performance I would never be promoted. Who would want to stay in such an environment?
