From Internship to Mentorship: Building Lasting Relationships with Supervisors & Colleagues

You successfully completed your internship, gained valuable skills, and hopefully made a good impression. That’s great! But the end of the internship doesn’t have to mean the end of the relationships you built. By using smart internship networking tips, you can potentially turn connections with supervisors and colleagues into valuable, long-term mentorships. Learning how to maintain these connections is key for building professional relationships that can support your career for years to come.
Your Internship: More Than Just Work Experience
While the projects you completed are important, the people you met and worked with are an equally valuable asset. Your supervisors and colleagues saw your work ethic, skills, and potential up close. They can become powerful advocates, advisors, and finding career mentors often starts here.

Why Cultivate Relationships Beyond the Internship?
Maintaining connections after your internship offers significant benefits:
- Mentorship: Gain ongoing advice and guidance from experienced professionals.
- Networking: Expand your professional circle for future opportunities.
- References/Recommendations: Supervisors who know you well can provide strong references or letters of recommendation later.
- Industry Insights: Stay updated on trends and developments in the field.
- Potential Future Opportunities: Staying connected might lead back to job openings at that company later.
Post-internship networking is an investment in your future.
Identifying Potential Mentors During Your Internship
While interning, pay attention to people who:
- Offer helpful advice or feedback.
- Take an interest in your learning and development.
- Share their career experiences openly.
- You genuinely connect with and respect.
- Are in roles or fields you aspire to.
Your direct supervisor is often a natural potential mentor, but other colleagues can be valuable too.
Strategies for Staying Connected After the Internship
The key is to stay in touch politely and periodically, without being annoying.
- Send a Thank You Note: Immediately after your internship ends, send personalized thank-you notes (email or handwritten) to your supervisor and key colleagues you worked closely with. Express gratitude for the opportunity and mention something specific you learned or enjoyed.
- Connect on LinkedIn: Send personalized connection requests on LinkedIn, referencing your internship. This is a professional way to maintain a link.
- Occasional, Relevant Updates: Every few months (maybe 2-4 times a year), consider sending a brief, professional email update. Examples:
- Sharing a major relevant academic achievement (e.g., “Just wanted to let you know I declared my major in X, partly inspired by my work on the Y project during my internship.”).
- Congratulating them on a company achievement you saw in the news.
- Sharing an interesting article related to their field (if appropriate).
- Asking a brief, specific question (see next section).
- During holidays, a simple “Hope you have a great holiday season!” can maintain connection.
Keep these check-ins brief, professional, and focused – don’t overwhelm them.

Nurturing the Relationship: How to Ask for Advice
Once you’ve maintained a light connection, you can occasionally reach out for specific advice – transitioning from connection to internship to mentorship.
- Be Specific: Don’t ask vague questions like “Can you be my mentor?”. Instead, ask for advice on a specific challenge or decision (e.g., “I’m choosing classes for next semester and wondering if you have any advice on courses valuable for a career in X?” or “I’m starting my job search in Y field and remembered you mentioned Z – would you have 15 minutes for a quick chat sometime?”).
- Respect Their Time: Keep requests for advice concise and make it easy for them to respond (e.g., offer specific questions, suggest a brief call).
- Show Gratitude: Always thank them for any advice or time they offer.
Giving Back: Being a Good Mentee
Mentorship is a two-way street, even if informal.
- Be Prepared: When asking for advice, do your homework first.
- Follow Through: If they give advice or suggest an action, consider it seriously and let them know how it went (if appropriate).
- Offer Help (If Possible): As you progress, if there’s ever a way you can assist them (e.g., connecting them with someone, sharing relevant info), do so.
- Be Respectful: Value their time and expertise.
Final Thought: Turn Connections into Lasting Support
Your internship provides a unique opportunity to build meaningful professional relationships. By using thoughtful internship networking tips for staying connected after internship periods and respectfully seeking advice, you can nurture these connections. Turning internship contacts into lasting mentors requires effort and professionalism, but building professional relationships like these can provide invaluable support throughout your career journey.
