On the last Thursday of each July, we celebrate National Intern Day, which is the perfect time to take a closer look at your resume and make sure you’re showcasing your new skills and knowledge effectively. Hiring managers will want to see that you’ve made an impact, and it can be far too easy to undersell your internship on your resume.

What Did You Contribute?

Before you even start putting together your resume, ask yourself: What did I contribute to the team? The answer to this question will be the basis for how you include your internship experience on your resume.

Maybe you helped solve a problem, saved your team valuable time, improved upon a process, or added value in another way. The point is, thinking about the big picture will help shape the tone of your resume. Along with this, you’ll be writing with a results-first mindset, which will greatly enhance your resume.

What Did You Accomplish?

When crafting your resume, avoid using passive, vague language. Some examples of this might include phrases like “helped with," “supported,” or “worked on.” This kind of language won’t tell recruiters much and will only make your resume forgettable.

Instead, start each bullet point with a strong action verb, and focus on what you did and delivered. This will demonstrate confidence and ownership, which are two incredibly important and valuable qualities. Check out these examples of a weak bullet point versus a strong one:

  • Weak: Helped with social media posts for marketing team.
  • Strong: Wrote and scheduled 15+ Instagram posts that increased engagement by 12% in one month.

Show Evidence of Learning and Initiative

You don’t have to prove full ownership of a major project, but employers still want to see that you picked up new skills and industry knowledge. Along with this, it’s important to show that you were proactive during your internship.

The bottom line is interns who can show growth and a willingness to learn stand out to hiring managers. Let’s say you interned at a tech company and took customer service requests. Here, you might say “Took initiative to audit 100+ customer support emails, identifying recurring issues that led to an updated FAQ resource.”

Resume Bullet Point Examples by Field

To help you get started, here are some sample bullet points organized by common career areas:

  • Conducted competitor analysis and presented findings to marketing team leadership.
  • Wrote 10+ blog posts and social media captions aligned to brand voice and SEO best practices.

Tech/IT Intern

  • Identified and fixed bugs in front-end codebase, improved load speed by 22%.
  • Collaborated with product and UX teams to test new app features before launch.

  • Reconciled monthly expenses across three departments using Excel tables.

  • Analyzed employee engagement survey data; presented findings in team meeting.

Tailor Your Resume

Just like a cover letter, your internship section should change slightly depending on what job you’re applying for. You might swap different skills or tools you learned, or you might share different experiences depending on the job description.

The key is to ensure that your resume aligns with the job description. For example, if the description mentions “data analytics,” highlight any work you’ve done with Excel. If the description mentions “teamwork,” emphasize collaboration or cross-functional projects. This philosophy applies to every role and industry, so be sure to read job descriptions carefully.

Internships are often the first real test of how you’ll perform in the workplace, so it’s incredibly important to properly convey your role, what you learned, and how you contributed to the team. Think of your internship as a “preview” of your potential, and don’t sell yourself short.
