The Finish Line: 4 Steps to Take After Your 12-Week Internship

07 July 2026

A young, confident-looking female intern is standing facing and smiling at the camera with a team of professional people in the background.

Congratulations! You have completed 12 weeks of work experience. Whether you spent your time at a big company, a small business or even a small startup, you would have gained many insights into the working world. You’ve survived deadlines, learned how a real team operates and developed new, work-related skills and habits.

Did you know that your internship experience shouldn’t come to a full stop on the last day. Many student interns make the mistake of closing their computers on the last Friday and forgetting about their internships by Monday. Instead, the final week is your chance to turn that experience into future opportunities.

An internship is more than a university degree requirement. If you play it well, it can act as a launchpad for your future career. Here is a simple guide on how to wrap up your internship professionally, that is, how to reflect, update your profile and prepare for your next big move: graduation and stepping into the workforce.

1️⃣ Pause and reflect on your internship

First, reflect on your internship experience. Before you jump into your next university project or start applying for jobs, take an hour to sit down with a notebook. Reflection is key to personal and professional development and success. Ask yourself the following three questions:

What did I enjoy the most?

This question helps you understand your interests and better direct your efforts towards your future career path. If you loved analysing data but hated writing emails, you have a better idea now what kinds of jobs might be more suited for you. Mind you, email writing is required in every job, so the other thing to think about is how to improve yourself in the areas that you don’t like so much.

What was difficult?

This question helps you figure out your weaknesses and areas where you need more training or practice (such as writing those emails…). Think also about the tasks, and even situations, that were difficult for you and which you did not like so much. Try to also think WHY those things were difficult or unpleasant and how you could improve on them.

What were my achievements?

Think of moments where you solved a problem, helped a team member or created something from scratch. Write down these achievements now while they are fresh in your mind. You will need these stories during future job interviews when hiring managers ask, "Tell me about a time you overcame a challenge."

2️⃣ Turn your internship experience into practical results

Next, update your CV and LinkedIn. Your internship is now an asset on your resume. Go beyond listing your internship role title and the company name; you need to show your impact. Future employers want to see results. They won’t be interested in a list of daily tasks.

When updating your CV or LinkedIn, be as specific as you can. Numbers catch a recruiter's eye better, so try replacing general phrases with measurable achievements. Here are some examples:

Instead of saying: "Helped with marketing"
It's better to say: "Created ten (10) social media posts that reached 5,000 users."

Instead of saying: "Assisted with accounting tasks"
It's better to say: "Reconciled 50+ monthly bank statements and identified five (5) balance discrepancies."

Instead of saying: "Worked on engineering projects"
It's better to say: "Assisted in testing three (3) product prototypes and documented 12 technical compliance reports."

Overall, use action words: start your bullet points with strong, professional words like organised, developed, researched or assisted. You can also update your LinkedIn profile with three to five (3-5) new skills you practiced during the internship, such as project management, data analysis or customer relations.

3️⃣ Don’t be shy: ask for a recommendation

Consider asking for a recommendation. A supervisor’s praise is great proof of your aptitude and work-readiness. Future employers are likely to trust what your internship supervisor says about you much more than what you say about yourself.

Don't be afraid to ask for a reference before you leave. Send a polite, short message to your supervisor. It could be something along the lines "I really enjoyed working with you. Would you be open to writing a brief recommendation for my LinkedIn profile?".

A reference letter can be helpful, if you plan to apply for full-time jobs soon, so ask for a formal PDF letter that summarises your strengths, reliability and technical skills. This is assuming that you did well in your internship. Remember, your supervisor will have to be honest in any references they may give, so make sure you earned a good word from them.

4️⃣ Close the chapter professionally and stay connected

Finally, close your internship chapter professionally and in style. The way you leave the host company is just as important as how you started. You want your supervisor and colleagues to remember you well.

Make sure your manager has access to all your files, documents and passwords. Do not leave any unfinished tasks behind without handing them over to a team member and don’t leave any messy folders or piles of filing behind.

On your last day, send a farewell email to your team. Thank them for their time, patience and mentorship, anything relevant and good that you experienced with them or with their help. It will leave a great impression. Suggest to stay in touch with the people you connected with well and connect with those colleagues on LinkedIn.

Remember that the student intern of today can be the full time colleague tomorrow (well, after graduation anyway)! If you stay in touch with your colleagues, you might just get a heads up when a role opens up in the company in the future.

What's next?

Well done for completing your internship placement. You are now so many experiences richer. Be sure to finish your internship in style: reflect on what you’ve learned, update your CV, get a reference and stay in touch with your colleagues and contacts. This way you’ll put yourself ahead of the game and can pave the way for a successful start as a new graduate.
