Pros
Challenging work. Unique work. I wasn't sure exactly what to expect when I joined but things have worked out pretty well. It's almost like a cross between finance and the law. Is the work sometimes repetitive? Yes, but that is the nature of preparing reports for litigation, as everything has to be 100% perfect or the expert (my boss) will get killed on cross examination. Like a lot of professions this one gets more interesting as you stick with it since you have more client-involvement and higher level work. Work/life balance is good. I have had some 80 hour weeks and some weekends, but I also have had lots of "easy" weeks and have taken several weeks of vacation a year.
Cons
As others have mentioned, 401k match is lacking. The monthly firm outings have also seemed to have dropped to every other month and I wish we still went out every month. It would also be nice to get together with the other offices (we have offices in several cities) more than just once or twice a year. Maybe we should have at least three all-firm get togethers a year, one in each of the major offices.
