Top Tier people. Co-workers are smart, engaging, and generally all team players. Hours and demands can be challenging and all encompassing, but you will be around people who will give you as much leeway as needed to make the experience as pleasurable as possible. Also, great benefits for young lawyers including nearly limitless business development account, and cart blanche to go to any industry / networking events, travel to meet clients or counter-parties, et cetera. They also invest heavily back into themselves, so offices, work environment, events, and fringe benefits are top notch.
Top Tier; firm will give you every monetary advantage to build your career
Hours; Offices can be somewhat segregated into mini-firms rather then one national team
