Pros
PFV has an immensely solid knowledge base in managed markets. It's also expanding at a fast rate. There are a lot of smart, good, decent people there, and for a managed markets house the work is varied and interesting. A good place to learn a lot. They make a lot of effort with corporate culture, parties and monthly prizes and awards and stuff. They give bonuses-- 8-12% of yearly salary, depending on position. The company that owns it has offices in various places which means you can actually move to a bunch of different locations if you fit what they need, and people do.
Cons
Management never shuts up about work/life balance but that's all they do, is talk. Rapid expansion of workload without rapid expansion of workforce. Some old-timers still harbor the idea that they're a boutique agency (maybe they were once, but not anymore) and as a result staffing doesn't expand as workload triples. This adds up to late nights, high pressure, and high attrition rates. Account execs burn out their assistant AEs by the carloads. Nobody ever has time to do anything good.
