Internship & Co-op Guide
Real engineering experience starts before you graduate. This guide covers the difference between internships and co-ops, when to start applying, how to build your resume, and what to expect in interviews.
Internships vs Co-ops
Both give you hands-on engineering experience, but they differ in length and structure.
Internship
Typically 10–12 weeks during the summer. You work full-time on a team, then return to school in the fall. Most students do 1–3 internships before graduating.
Co-op
Usually 4–6 months, alternating semesters of work and school. Co-ops give you deeper experience at one company and often lead directly to full-time offers.
Timeline
Starting early gives you a significant advantage. Here is a semester-by-semester roadmap.
Freshman Fall
Join engineering clubs, attend career fairs, and start building your network early.
Freshman Spring
Build your first resume and apply for summer research positions or lab assistant roles.
Sophomore Fall
Target your first internship. Polish your resume and prep for career fair conversations.
Sophomore Spring
Interview season. Practice behavioral and technical questions, then accept your best offer.
Junior & Beyond
Pursue more competitive positions, take on leadership roles, and build toward full-time offers.
Building Your Resume
Your resume is usually the first thing a recruiter sees. Keep it to one page and focus on these four sections.
Education
GPA (if 3.0+), relevant coursework, honors, and expected graduation date.
Projects
Class projects, personal builds, and competition entries. Quantify results when possible.
Skills
Software (MATLAB, SolidWorks, AutoCAD, Python), lab equipment, fabrication tools, and programming languages.
Leadership
Club officer roles, team leads, tutoring, mentoring, and volunteer work.
Tip: one page is the standard for students and early-career engineers. If you cannot fit everything, cut the least relevant items first.
Interview Prep
Engineering interviews usually combine behavioral, technical, and design questions. Preparation makes a noticeable difference.
Behavioral Questions
Use the STAR method (Situation, Task, Action, Result) to structure your answers with concrete examples.
Technical Questions
Review fundamentals from your major courses - statics, circuits, thermodynamics, or whatever applies to the role.
Design & Case Questions
Think out loud, sketch diagrams, and walk the interviewer through your reasoning step by step.
Questions to Ask
Ask about team structure, day-to-day work, mentorship, and what a successful intern looks like.
Where to Find Opportunities
Cast a wide net. The best opportunities often come from multiple channels at once.
Your university career portal and Handshake are great starting points, since many companies post positions exclusively through campus recruiting platforms. LinkedIn is valuable for finding openings and connecting directly with recruiters and engineers at companies you are interested in. Do not overlook company career pages, where some of the best positions are posted before they hit aggregator sites. Engineering career fairs give you face-to-face time with hiring managers, and professor recommendations or lab connections can open doors that are not publicly advertised.
