Pros
HNTB works on interesting and large scale projects. These projects are good resume builders. HNTB is has a pretty relaxed environment; friendly people, allow casual dress a lot of the time. A couple times a year each company branch office meets and talkes freely about strategies with developing technology and client relationships. It was nice to see that everyone was included to some degree in the operations of the company. There is a nice mix of younger professionals and seasoned professionals to form working groups and act as specialized teams. Also, the Kansas City offices are located in nice building downtown, and in overland park.
Cons
I worked for HNTB Federal which seemed to have unpredictable work loads. Many of the projects are quick design build projects that are bid low and expected to be completed within a couple weeks. There are many engineering companies that are struggling, but while I was there over 1.5 years they grew rapidly (over doubled in size), and didn't seem to plan for new hires beyond their current work needs. I like the idea of having work 'teams' but many times it was unclear what my team was or who my boss was , or what project I would be working on.
