Oops! Something went wrong while submitting the form.

Your internship application is more than a form; it’s your first real shot at standing out. But even strong candidates lose out on opportunities because of small, preventable errors. Fortunately, most of these mistakes are easy to fix once you know what to look for. Here’s how to avoid them and submit an intern application that gets noticed.

Top Mistakes Students Make on Internship Applications

Even the most qualified students can get overlooked because of small, avoidable missteps. One common mistake in internship application submissions is sending a generic resume or cover letter. Hiring managers can tell when you're recycling the same content, and it doesn’t help your case.

Another red flag? Errors. A typo or mismatched company name might seem minor, but it can make your intern application look rushed or careless. Always take time to proofread – you can use tools like a GPT to help catch small mistakes, and if possible, ask someone else to review your materials before you submit.

Timing is important, too. Waiting until the last minute can mean missing rolling deadlines or competing for fewer open roles. A thoughtful, early internship application shows that you’re prepared and genuinely interested.

And perhaps most important, make sure your materials tell a story. Don’t just list your experiences; connect them to what the company is looking for. Even small improvements can help you avoid common pitfalls and make your application much stronger. For more advice, check out our blog on crafting a standout resume. 

What Makes a Strong Internship Application?

A strong application for an internship reflects thoughtfulness and preparation. That starts with being selective. Focus on internships that genuinely align with your goals, rather than applying to every listing you find.

Then, customize everything. Use keywords from the job description, emphasize relevant skills, and tailor your story to show how you fit the role and company.

Don’t overlook the details. Some internship applications require a transcript, writing sample, or even a short essay. Make sure you’ve included everything requested before hitting submit.

Beyond the Application — Standing Out & Building Your Future

Once you submit your application for internship positions, your work isn’t done. Now’s the time to build on your momentum and prepare for what comes next. Start with interview prep; review your materials, practice common questions, and be ready in case you get a response sooner than expected.

Make sure your digital presence is up to date. Refresh your LinkedIn profile, clean up your social media, and ensure everything reflects the professional image you want employers to see.

If you’ve already applied, don’t go silent. Reach out to anyone in your network who might have a connection at the company; you can still flag your interest and keep your application top of mind.

Finally, follow up with professionalism. A well-written thank-you email or a timely check-in shows maturity and keeps you on the employer’s radar. For more tips, check out our guide on professional etiquette
