Pros
Having worked in a few different environments (government, large corporation, small consulting firm), I have a strong appreciation for the environment here. While it is a demanding workplace (high expectations for work quality and dedication), those demands are balanced very well by a supportive, friendly, team-oriented, family-like culture. The founding partners are still very involved, with lots of contact with all employees. They take very seriously annual reviews and use them as an opportunity to help grow people and build careers. I now work in a different department than the one I started in, as we realized that there were other areas better suited for my personality/skills/ambitions. This hands-on management and creative flexibility is a big part of creating loyalty and success. The company has grown quite a bit over the past five years, and that is exciting and has created new opportunities for everyone. Even with that success, senior leaders have a roll-up-your-sleeves attitude to lead by example and ensure that newer folks get the support they need. Five years in, and I've never thought about looking elsewhere!
Cons
The business has a heavy busy season that hits different departments at different times. Those periods can be quite demanding when you go through them. But other departments always rally to provide support and the periods pass quickly, with far less demanding ones taking their place.
