Pros: benefits, working with students
Pitt is a stable place to work, and the benefits are decent. Tenure track professors are well-treated and reasonably well-compensated.
However, it is becoming more and more difficult every year to become a tenured professor, and many instructors, adjuncts, and non-tenure track hires do the bulk of the work in a department. Frequently, the tenured professors will have awesome ideas for improving programs and processes, however they have no intention of contributing to the work that will make these improvements happen.
This contributes to general disgruntlement among the harder-working academes, who teach, advise, do research, write papers, serve on committees, supervise students, travel to conferences, and generally run the place.
Oh, and by the way - after you earn that PhD and get a job here, you'll be making your own copies, and walking your own forms over to the library. The secretaries don't work for you, they work for the tenured and administrative professors.
