Pros
Is a friendly firm that seems to punch above its weight, so it does give confidence in Senior Management. Is not a firm that works you hard so work-life balance is good, although likely to change with the outdated desire to have people in the office more. Individual teams get on well and is one of the few firms I would say where 99% of employees are approachable. Death in Service pay out benefit is probably the best I have ever seen.
Cons
Is very lawyer centric (as most firms are). No bonus for business services and budgets for back-office department "do's" are very small so ultimately I have no real feel or care for the firm so long as I get paid. Having a Partner heavy setup, being their USP, does seem odd and some of these Partners are most definitely overpaid and would be better as in-house lawyers rather than working for a law firm.
