What is a Computer Science Intern job?

A Computer Science Intern is a temporary position where students or recent graduates gain hands-on experience in software development, data analysis, cybersecurity, or other computing fields. Interns typically assist with coding, debugging, research, and testing while working under the guidance of experienced professionals. This role helps build technical skills, industry knowledge, and networking opportunities, preparing interns for full-time positions in the tech industry.

What kind of projects and tasks can I expect as a Computer Science Intern?

As a Computer Science Intern, you can expect to work on a variety of tasks such as writing and testing code, debugging software, supporting ongoing development projects, and collaborating on team-based assignments. Interns often contribute to designing features, fixing bugs, conducting research, or assisting in quality assurance under the guidance of senior engineers or mentors. The exact nature of your projects may vary based on the company and team, but you will typically gain hands-on experience with real-world software development tools and workflows. This exposure not only builds your technical skills but also helps you understand agile work environments and best practices, making it a valuable step toward a full-time role in the field.

What are the key skills and qualifications needed to thrive in the Computer Science Intern position, and why are they important?

To thrive as a Computer Science Intern, you need a solid understanding of programming languages (such as Python, Java, or C++), data structures, algorithms, and basic software development principles, typically backed by ongoing coursework in computer science or a related field. Familiarity with version control systems like Git, integrated development environments (IDEs), and sometimes exposure to cloud platforms or coding certifications can be advantageous. Strong analytical thinking, effective communication, initiative, and the ability to work well within a team are valuable soft skills in this role. These skills and qualities ensure that interns can quickly contribute to projects, adapt to new technologies, and collaborate effectively with experienced professionals.

Job description

If you’re looking to hit the ground running, the Enterprise Management Internship will help you build valuable business and leadership skills. For a university/college student, the real-world professional experience you’ll receive during the internship will help you stand apart from the crowd, and will be more than just a line on your resume.

From day one as a paid intern with Enterprise, you'll learn what it takes to run a successful business and acquire highly marketable skills in management. Our university/college interns take on the same challenges as our first and second year full-time professionals. It's a team-based environment; and throughout your internship, your peers will be right by your side helping you learn, grow and have fun.

This is a Part-Time position, slated to start Tuesday, September 1st and last for 90 days.  This role is located at our rental office in Decatur, IL - 2745 N Water St, Decatur, IL 62526.


When you join our Management Internship Program, you'll soon discover that every day is different because it is filled with new, exciting, rewarding and often unexpected opportunities. For a season, we’ll put you in the middle of everything, just like our Management Trainees. We’ll give you the chance to develop the skills you need to manage a fleet of vehicles, take care of customers, develop marketing strategies and build relationships with customers and coworkers.

During our internship, you’ll use the skills you learn to complete intern projects and engage in some friendly competition with your peers. You may also be eligible for performance incentives and employee referral rewards.
