Pros
Friendly and collegial work environment. Unlike many law firms, it isn't stuffy or confined by the typical set of "rules" many traditional law firms operate under. It is run like a business that just happens to be a law firm, which is great since it allows firm attorneys to better understand the business of practicing law. Also, there is a strong focus on timely client and colleague communications, which is always important in building long-lasting relationships. Lastly, great work life balance, particularly for a law firm.
Cons
Vary occasional late nights or weekend work required, but this is expected for any business-focused law firm handling M&A and private equity work.
