I have been working at Whiting-Turner full-time (More than a year)
Plenty of oppurtunity for growth - they give you the oppurtunity to bite off as much as you can chew. Raises and promotions follow. Working on the jobsite - and within your group - one truly experiences a small business feel. Also, there is plenty of job security, especially if you're willing to travel.
Paying subs can be a pain due to Whiting-Turner's size - and the bureaucracy that follows. Subs can get very nasty if not paid in a timely fashion.
Advice to Management
Offer a raise or promotion if you elect to move an individual to another state with a weeks notice.
I applied through college or university. The process took 2+ months. I interviewed at Whiting-Turner (Greenbelt, MD) in October 2015.
I met some of the Whiting-Turner members at a Career Fair at my college and was asked to have an on campus interview the next week. Both interviewers were laid back and conversational. I was then asked to come in for a second round interview at their office in MD. There I talked to three different people, including two Vice Presidents. All three were also very conversational. They asked some typical interview questions regarding my interests and why I wanted to do construction and why Whiting-Turner, that kind of stuff. They also asked lots of questions about my resume and allowed me to expand on my experiences. They were also very open to answering my questions. I was asked to come back to visit a job site with them.
