• Class year: sophomores, juniors, and seniors pursuing a bachelor's or master's degree.

• Driver's license: valid license with reliable transportation required for field/operations roles. Projects may be in remote locations (wind farms, solar sites, data centers).

How Demanding Is a Mortenson Field Internship?

Honest answer: very. Reddit and Indeed reviews consistently describe Mortenson as a company that works hard. Field interns work construction hours (starting 6 to 7 AM), and 50-plus-hour weeks are common in the industry. One Indeed reviewer called it "trial by fire" for new hires. But the training is exceptional, the projects are iconic, and the company's 4.1/5 Indeed rating with 4.1/5 on pay and benefits reflects that the trade-off is fair. If you want a comfortable desk internship, this is not it. If you want to build stadiums and solar farms, this is exactly it.

What Skills Does Mortenson Look For, and How Do You Build Them?

Mortenson sits at the intersection of traditional construction operations and technology-forward innovation, and its intern hiring reflects that duality. Across field and corporate tracks, the pattern is clear: safety consciousness appears in every role, project management and analytical thinking are universal, and the company's push into data centers, AI, and renewable energy creates demand for technical skills alongside construction fundamentals. What does this tell you? Mortenson hires people who can combine hands-on construction sense with the analytical and technological capabilities that modern construction demands.
