Pros
Compared to others in the industry, Kimley-Horn has a very strong total compensation package. The highlights of the package are the profit sharing (~17%) and the bonuses. I think they try to keep the salaries around the industry average. The corporate culture is very strong and really emphasizes the develpment of each employee. The training at Kimley-Horn is somewhat limited but they are making an effort to improve in this area.
Cons
Expect to spend most of your time chugging away at a computer for the first 4-5 years. The promotions can get a little political - I was very disappointed to the the promotion of somebody that stepped on others toes to rise to the top. The "extra-effort" culture can get a little annoying - mostly because the regional team micromanages everybody's billable hours. I am not sure that the company is going in a good direction. There are going to be some growing and adjusting pains as the company reaches a critical mass for the small markets which they typically serve and start to seek out the larger projects. They are starting to win projects with the big players in the industry and in so doing are becoming more similar to the big players (i.e. hiring big wigs with big names to win the big projects and moving people around to serve projects)
