Pros
The individual people tend to be pretty nice as people; few yellers. If you know someone, you could get some decent work. If you're willing to put your pesonal life on hold for below-market pay, you'll be happy here.
Cons
Not enough work; low quality work that paralegals should be doing but is forced on associates to jack up billings; complete lack of transparency not just on salaries but on general firm policies; bad review system without substantive critique where employees are pressured not to request reviews; partners have little to no interest in associate development; lack of mentorship; associates blamed for partners' lack of interest in mentoring (yeah, it's a two way street, so don't blame associates for 100% of the problem); firm has little to no interest in associate developement; few to no skill building experiences; very political (it's about who you know and who likes you); absurd level of kool-aid drinking attitude expected of you; expectation that you will 100% of the time drop your personal life on weekend's at a moment's notice. Firm's public stance on diversity and quality of life don't match up with inehrent realities. Granted, some of these problems are pretty common at any big law firm--Jones Day's environment at my office is just pretty depressing. It's a revolving door of associates; don't plant to be here for more than a pit stop on your way to a different job. Little to no feeling of job security, but they still expect you to devote your professional and personal life to the firm even as they plan to kick you to the curb...
