Pros
Privately owned company (double-edged sword, but largely in good ways) that genuinely has a lot of the nice versions of work family vibes. People who've been there for years, know each other besides just as coworkers, and a lot of shared passion for the industry they're in.
Cons
Can shift very quicky in many ways, some management make decisions without as much oversight or communication/discussion as would be wise. HR goes by people and culture, but operates as any classical HR department otherwise would/does.
