Navigant hires bright, motivated people and gives them room to grow. Several training opportunities if you seek them out. Also, some practices are better than others at providing mentorship.
Culture is very collaborative in larger offices. Smaller offices tend to be single-practice, and up to that office's leadership.
Corp management struggles to meet demands of investors (bottom line) and still provide a place where directors have the flexibility to create their own practices.
I'd recommend this company to a self-starter, and willing to speak up for assistance, training, and guidance.
