About your past
This supports design, construction and operation of a county highway system. What interests you about public sector civil engineering rather than private practice?
What they are checking: Genuine interest in the public infrastructure setting this posting emphasizes.
Tell me about a project in your coursework where the calculation and the practical reality did not match.

What they are checking: Whether they know what they want from the summer, since a busy season goes better for interns with clear goals.
This is one of two summer internship openings with the county's public works engineering division, paying $12.71 to $22.52 an hour. What do you want to know about the split between office and field work, and what sets your place in that range?
What they are checking: Checking the work mix and the unusually wide stated band.
What would you do
You are sent out to a construction site to observe. What would you be looking at?
What they are checking: Whether they would notice what matters on a construction site, since field awareness shows how quickly an intern will learn.
The posting says you would train and guide student peers. How would you teach someone something you only learned last week?

A contractor tells you something is fine that you are not sure about. What do you do?

How do you keep field notes so someone back in the office can use them?

What software have you used, and what would you want to get better at this summer?
What they are checking: Whether they are honest about their skills and want to grow, since internships work best when goals are clear from the start.
