Vantaggi
The only reason I can see for the negative reviews is that you actually have to work hard! This company is the best in class when it comes to private hc communications- we are buttoned up and work fast paced, so if you're not intelligent/passionate/professionally driven... you will not last. It's an environment of excellence, not just 9-5'ers. And Sr management is always available to help the new faces - there's truly endless support and coaching.
ALL are given the opportunity to succeed, to be heard. Yes, it's hard work, but no one is alone. We have a reputation for being the best, and that needs to be maintained.
A truth you don't hear often is how compassionate the family owners are - because they don't publicize their good deeds. They're incredibly compassionate - they're just stoic, so you wouldn't assume how philanthropic they truly are.
Svantaggi
Since there are a lot of people right out of college, those folks are usually new to corporate, and therefore don't realize that you're expected to work hard in corporate! This is to be expected, but it contributes to the glass-half-empty theme on Glassdoor. The complainers are the ones that haven't realized the grass isn't greener. They'll learn eventually!
Since the work is hard, burn out happens. This is the price for opportunity, however.
And the usual small company woes - benefits could improve, but they likely will as we grow (new acquisition).
