How to Build Your Professional Network in a 12-week Placement
25 June 2026
Starting an internship is an exciting step for your career development. You get to see how a business operates, use your university knowledge in real situations and learn new skills. Many students think that an internship is about completing tasks and building skills. However, the relationships you build during these three months can be just as important for your future employment as a new graduate.
You don’t need to attend large industry events or join external professional bodies to start building your network. The most important people for your professional future might already be in the same workplace as you. They are your supervisor, your teammates and the professionals working in other departments.
This guide shows you how to turn your daily internship interactions into meaningful professional connections before your 12-week placement finishes.
Why your immediate team is your best networking asset
When you work with people every day, they get to see your work ethic, your communication style and your ability to solve problems. This makes them the perfect addition to your professional circle.
Building a network is about being helpful, asking good questions and showing interest in other people and the work others do. Instead of trying to impress everyone with complex industry jargon, for example, it’s better to be real and genuinely interested in what’s going on around you and in the industry.
People enjoy sharing their knowledge with interns who want to learn. If you show a positive attitude during your 12-week placement, your team members are more likely to be happy to assist you in the future.
How to ask a colleague for a career chat
One of the best ways to learn about your industry is to talk to the people who are already doing the job. You can do this by asking a colleague for a short career conversation.
It can feel intimidating to ask a more experienced, perhaps more mature colleague for a chat, especially if English is your second language. The good news is that most people feel flattered when someone asks them for advice. So go for it!
Step 1: Choose the right person
Look around your department. Is there someone who has a job that you would like to have in five years? Is there a colleague who recently finished university and understands your situation? These are the best people to approach.
Step 2: Send a short message
Rather than walk up to their desk anytime, let alone while they are clearly busy and ask for a meeting, find a good moment when they are free to approach them. It could be in the break out room or the shared kitchen.
If your colleague is located in a different part of the building or is rarely on site or in meetings most of the time, you could also send a polite message via email or your company communication tool, such as Microsoft Teams or Slack to ask to meet with them. Keep it clear and short.
Here is an example of what you can say:
"Hi ____________, I hope you are having a good week. I am the new marketing intern. I really enjoy seeing how you manage the company's social media campaigns. I would love to learn more about your career path. Do you have 15 minutes for a quick coffee or a virtual chat sometime next week? I would appreciate your advice."
Step 3: Prepare your questions
When they say yes to meeting you, make sure you respect their time by being prepared. You are the one who asked for the meeting, so you need to lead the conversation. Bring a notepad and pen to write down notes. Here are a few great questions to ask during your chat:
● What does a typical day look like in your role?
● What skills do you use the most in your daily work?
● What advice do you have for a recent graduate entering this field?
How to expand your network beyond your own team
During your internship, you are likely to interact with people from other departments. You might meet them in the lunchroom, in the lift or during cross-department meetings. These casual moments are excellent opportunities to expand your network.
The lunchroom introduction
If you see someone eating lunch or making coffee, do not be afraid to say hello. You can use a simple script to introduce yourself.
For example:
"Hello, I am ___________. I am the engineering intern working with the operations team for the next three months. Which department do you work in?"
This kind of introduction can open the door to an interesting conversation. You will learn about your colleague’s work and how different parts of the business connect with each other, which expands your business knowledge.
How to connect with team members on LinkedIn
LinkedIn is the tool that keeps your network alive after your placement ends. If you do not connect with your colleagues on LinkedIn, you might lose touch with them once you return to university.
Do not wait until your final day to send LinkedIn invitations to everyone you made a good connection with in the host company. Start connecting with people as soon as you have worked with them or after you have had a career chat.
On Linkedin, always add a personal note
When you send a connection request on LinkedIn, always include a short, personal message. This reminds the person who you are and shows professional courtesy.
Here is an example for a close teammate:
"Hi ______________, thank you for all your help during my first month at the company. I am glad to have you in my professional network."
Here is an example for someone you had a career chat with:
"Hi ______________, thank you for taking the time to share your career story with me last week. Your advice about learning data analytics was helpful. Let us stay in touch here."
Action plan for your 12-week internship
To make this process easy to follow, here is a timeline of how you can build your network week by week during your placement.
Weeks 1 to 4: The foundation
Focus on doing your daily tasks well. Learn the names of your teammates and understand their roles. Say hello to people in the common areas and show a friendly attitude.
Weeks 5 to 8: The career chats
Identify two or three colleagues whose work interests you. Send them a message to ask for a 15 minute career chat. Conduct the meetings and send a thank you email the next day.
Weeks 9 to 12: The digital connection
Connect with your colleagues on LinkedIn using personalised messages. Write a nice farewell message to your team on your last day, thanking them for the opportunity, and invite them to stay in touch.
Final thoughts on internship networking
Building a professional network does not require a complex strategy. It is the result of small, polite actions that you take every day during your placement.
By showing genuine interest in your colleagues, asking for career advice and connecting on LinkedIn, you start creating a supportive network of professionals who can perhaps mentor you and help you find job opportunities in the future.
