🌞 Summer Internship Applications: Ultimate Do’s & Don’ts

Landing a great summer internship doesn’t happen by luck—it takes strategy, focus, and knowing exactly what to say (and what not to do). Whether you’re aiming for a role at a Fortune 500 company or a small nonprofit, these tips will help you stand out for the right reasons.


βœ… THE DO’S: How to Get Noticed


1. 🎯 Target Your Interests (Quality Over Quantity)

Apply smarter, not harder. Instead of spamming 100 random applications, focus on internships that truly align with your values and long-term goals.

Action Steps:

  • Research 10–15 companies in your field of interest.
  • Prioritize those where you can contribute meaningfully.
  • Track application deadlines in a spreadsheet.

Pro Tip:

Use LinkedIn to reverse-engineer your path—check the internship history of professionals who have your dream job.


2. πŸ“„ Craft a Strong Resume (Show, Don’t Tell)

Your resume is your handshake on paper. Make every line count.

Highlight:

  • Relevant coursework (e.g., “Intro to Python” for tech roles)
  • Quantifiable impact (e.g., “Reduced wait time by 20% through new workflow system”)
  • Soft + hard skills (e.g., teamwork, Canva, SQL, data analysis)

Template Example:

Marketing Intern 

XYZ Nonprofit | Summer 2024 

- Designed a 3-week social media campaign that increased engagement by 45%. 

- Conducted research on youth outreach strategies across 10 regional programs. 


3. ✍️ Tailor Your Cover Letter (Make It Personal)

Generic cover letters go unread. Customize each one with intent.

Suggested Structure:

  • Intro: Show genuine interest. Mention something specific about the company (a mission, news story, or project).
  • Body: Connect your experience to the internship description.
  • Close: Include a confident call to action.

Sample Opener:

"When I read about [Company]’s mentorship initiative for first-generation students, I knew I wanted to be part of your team. As a first-gen student myself, I’ve led peer mentoring sessions through [Program], which aligns closely with your goals."


4. 🎀 Practice Interviews (Outprepare the Competition)

Great interviews win internships—even over a flashy resume.

Common Questions to Master:

  • “Tell me about yourself” (Use Present–Past–Future format)
  • “Why this company/role?” (Tie to values and career path)
  • “Describe a challenge you’ve faced.” (Use the STAR method: Situation, Task, Action, Result)

Mock Interview Tools:

  • Big Interview
  • Your college’s career center
  • Trusted mentor or professor

5. 🀝 Network Actively (Your Secret Weapon)

80% of job opportunities come from connections, not job boards.

How to Reach Out:

  • Use LinkedIn to find alumni or employees in your field.
  • Message them politely:

“Hi [Name], I’m a [Year] studying [Major] at [University]. I admire your path in [Field]—would you be open to a quick 15-minute conversation?”

Bonus Move:
Attend virtual or local career fairs and always ask:

“What qualities make an intern successful on your team?”


🚫 THE DON’TS: Mistakes That Cost You the Internship


1. ❌ Dont Apply Shotgun-Style (Spraying ≠ Winning)

Mass-applying without customization is a waste of time.

Do This Instead:

  • Apply to 5–10 internships per week.
  • Tailor each resume and cover letter based on the job description.

2. ❌ Dont Submit Generic Materials

Hiring managers can spot “Ctrl+C/Ctrl+V” applications a mile away.

Fix It:

  • Match the keywords in the job listing.
  • Modify your “Skills” section per role (e.g., use “data visualization” for a business role; “data modeling” for engineering).

3. ❌ Dont Arrive Unprepared

If you don’t research the company, they’ll notice—and it’ll hurt.

Instead, Review:

  • Their website “About” page
  • Their most recent blog or press release
  • Key industry trends affecting their business

4. ❌ Dont Be Passive (Follow Up = Follow Through)

After applying, take initiative.

Follow-Up Email Template:

“Hi [Hiring Manager], I just submitted my application for the [Internship Title] role. I’m excited about the opportunity to contribute to [Project/Team Name] and would love to discuss how my experience in [Skill/Tool] could add value.”


5. ❌ Dont Neglect Your Online Presence

Your name will be Googled—make sure what they find helps you.

Cleanup Tips:

  • Set your LinkedIn to “Open to Work”
  • Use a clean headshot
  • Delete or hide any inappropriate public content
  • Consider creating a personal portfolio using Wix, Carrd, or Canva

🎁 BONUS: Internship Hacks That Give You the Edge


1. πŸ• Apply Early

Many internships (especially in tech or finance) close by March. Start your search in January or sooner.

2. 🏫 Use School Resources

Your college’s career portal may list internships not advertised elsewhere. Don’t ignore it!

3. πŸ’‘ Think Local

Email small businesses, startups, or nonprofits directly. Offer to intern on a specific project—you’ll often get a yes.

Real-Life Example:

“I cold-emailed a podcast producer with a pitch to help grow their social media. They brought me on for a summer internship, and now I freelance for them part-time!”


βœ… Final Checklist: Before You Hit Submit

βœ” Resume tailored to role
βœ” Cover letter personalized
βœ” LinkedIn cleaned up and current
βœ” Portfolio (if needed) linked
βœ” Interview prep practiced
βœ” Follow-up email ready


Bottom Line:

Internships are the launchpad for your career. Start with intention, apply with confidence, and follow up like a professional.
