Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
You are given a task and you do not understand why it is being done that way. What do you do?
What they are checking: Whether they ask thoughtful questions to understand why work is done a certain way, since in an operating plant there's usually a safety reason.
The start date is May 24, 2027. What do you want to be able to do by the end of it?
What they are checking: Whether they have a concrete goal for the internship term, which shows they'll use the experience well rather than just passing time.
What would you do
You'd assist project engineers with project management and execution. What does a capital project at a power plant involve that a classroom project does not?
What they are checking: Whether they understand that working plant projects face real constraints like safety and operations, which classroom projects rarely have to consider.
Work at an operating plant has to fit around the plant running. How would you expect that to change a project schedule?
What they are checking: Whether they understand that plant capital work must fit around outages and operations, which shapes every project schedule at a running plant.
A plant is an industrial site with real hazards. What would you expect to be your responsibility on safety as an intern?
What they are checking: Whether they take personal responsibility for safety at an industrial site, because plant hazards are real and safety habits matter from day one.
You'd need to commute to a plant in Becker, Mankato or Red Wing in Minnesota, or La Crosse or Ashland in Wisconsin. Which of those works for you?
What they are checking: The stated sites, raised plainly since it decides the offer
About the work
This internship supports capital engineering projects at coal-fired and refuse-derived fuel power plants. What do you know about how a thermal power plant generates electricity?

You'd learn project planning and budgeting systems. Tell me about tracking something against a budget.
What they are checking: Whether they have real experience tracking spending against a budget, since budget tracking is a named duty on capital projects here.
The posting requires sophomore standing or higher in an accredited program in electrical, mechanical, civil or chemical engineering. Where are you?
