Guide to Mechanical Engineering Internships (2025)

How to Prepare for a Mechanical Engineering Internship

It’s never too early to start preparing for your mechanical engineering internship. Major organizations may begin posting their summer internship openings on major job-recruiting websites as early as January. They may also offer internships in the fall and spring as well. While internships are generally reserved for juniors and seniors at the bachelor’s level, younger mechanical engineering students can get started early on building their resume and developing a professional network.

Typical requirements for mechanical engineering internships include: current enrollment in a bachelor’s or master’s mechanical engineering program; a competitive GPA (3.0 or greater); and full-time availability (over 40 hours per week) during the internship. Other potential requirements include: the ability to obtain US government security clearance (requires US citizenship); familiarity with CAD software; and coding proficiency. Any other relevant work or educational experience is a plus.

Top mechanical engineering internships can be extremely competitive, with the number of applicants far outweighing the number of available slots. It’s best to apply to several internship opportunities across different subdisciplines of mechanical engineering.

Fortunately, there are a wide variety of innovative and rewarding mechanical engineering internships available. To learn more, read on.
