Not a good place unless you are just starting your career or you are in senior management. There's a toxic positivity perfectly exemplified by the employee portal ("Connect" Facebook-like website). On this portal, there's an implicit expectation for employees to give effusive praise to the company and the management team. There's no space for employees who might have suggestions that might not echo management's stance in totality. In fact, any feedback that hits the level of tepid or lower is viewed as almost being insubordinate. I think some of the reviews on this site exemplify this (see the number of reviews with no cons listed).
This leaves room for 2 types of feedback; public and effusive praise, or anonymous, exasperated criticism. The "great place to work" designation is often cited as proof of a healthy culture, when in reality, the culture breeds "yes men/women". I'm not suggesting that all rank in file employees are unhappy, but I think the ones who are satisfied are also generally unmotivated to grow in their careers and are happy to just fly under the radar unnoticed.
This is also not to say that there are no people who are promoted from within, but the ones who do get promoted are generally defined by their willingness to embrace the mythology of "the IAT family"; not necessarily their talent level.
In a nutshell, if you want a culture that thrives on innovation and employee feedback, this is probably not the place for you.
