Pros
RSR is a special place to work. You feel genuinely cared about as an employee both by your peers and from management. Everybody, without exception, is kind and nice. From the top down there's a focus on helping you develop your career and giving you opportunities to challenge yourself. They've gotten a lot better at providing feedback via weekly 1-1s and quarterly 360 reviews. When all the stars align (right client, right project, right team), the work is incredible. Great opportunities to work with world-class brands, doing work that has real strategic impact, with a brilliant team of people that knows how to produce quality. One of the few companies I know of who not only talk the talk about diversity but have a very balanced and diverse workforce in practice (close to 50% gender balance, women in senior leadership, good spread of ages/seniority, etc). Has the perks of a startup type environment (dogs, ping pong table, liquor cart, occasional catering) but people are also professionals who are there to get stuff done. The hours are decent. 40-45 hour weeks are the norm, as with any agency biz there's occasionally crunch times but it's recognized and rewarded. Cash compensation is above market. Benefits are solid (401k with % matching, unusual for companies this size). Company regularly competes with and wins against larger, more famous agencies - and your role in the projects will be larger. A lot of independence and autonomy is given to you, but there's support and guidance to help you manage it. Clear growth plans and tracks for promotion. Talented junior employees can jump up a few ranks in their careers here. This place won Crains/AdAge "Best Places to Work in NYC" awards two years running for a reason. It's a great place to work and I'd highly recommend RSR.
Cons
Client base lacks focus, the wide range of clients (from huge banks to smaller non-profits) makes for variety but also means that every project is radically different. You learn a lot, but often it's not applicable to any future projects. Office is really spacious and beautiful but there's hardly any private space for calls/meetings/quiet time. The phone booths are not soundproofed. "Unlimited" PTO policy is confusing and shifts the onus onto managers to approve/deny vacation. Some guidelines for expected usage or setting a mandatory minimum would be helpful (generally vacation policy is relaxed and generous though). As with all consulting work, the team is at the behest of clients and their business cycles. Some clients are wonderful, some are dysfunctional in some manner. Sometimes the projects that pay everyone's salaries are boring. Sometimes there's not enough work to do and then there's too much work. This is the same at any client-driven service business though.
