Just like dating, finding the right employer can be very a difficult process. There aren't really any horrible employers/employees; more so a potential poor match.
As an intermediate to senior engineer, i now know what works for me and what doesn't. Though ztr has a lot of potential and good energy, they also have to realize that the (senior) people they hire potentially have more/better experience and ideas. But unfortunately, the politics is just a little too thick and the pecking order a little too overt. The company is not as open-minded and well managed as they would like you to believe. And there are also some sticking points in the managerial level... ie people who occupy a position that is far beyond their competency and qualification.
But hey, different strokes for different folks. I've served an average of 5 years in any given company, buy i had to quit this one within a matter of months. If I were a fresh grad, maybe things would've been different. But, it's always good to try things before you knock them.
Pros
Loyalty to employees, small company feel
Cons
Misallocation of skill sets, over-promoted manager(s), overly political, unnecessarily chaotic
