Pros
Like it was stated by others: some of the best co-workers one could hope for
Cons
Just go ahead and read every negative review that was posted here, it's really hard to top(bottom) them, but here goes: Bill Tan is a useless megalomaniac. The only three skills he has ever mastered are: 1. Milking the government (wake up NIH!) 2. Stringing together terms, buzzwords and random words, all framed in a pseudo-academic tone while being utter nonsense. 3. Sucking the energy and will power from all who around him. Bill Tan's sexist attitude toward women borderlines harassment at times. His capricious change of opinion - about any subject - feels like on some monthly cycle. Bill tan misappropriated government funds while maintaining a lavish lifestyle.
