Internship Dos and Don'ts: How to Be a Successful Intern

Quick answer: To be a successful intern, be on time, ask questions early, finish what you start and ask for feedback often. Do not hide mistakes, guess when you are unsure, or sit quietly when you have no work. Be curious, stay calm under pressure and treat the internship as a chance to learn, not only a route to a job.

I am Herlyn, Lead Community Manager at Asia Internship Program (AIP). I look after interns on the ground, so these tips are about what helps people settle in and do well at work.

Before you start

A little preparation makes day one much easier.

• Learn what the company does, who its customers are and what your team works on.
• Write down two or three goals, such as one skill you want to build and one person you want to learn from.
• Check the basics: where the office is, how long the commute takes, what time you start and what to wear.
• Read about local work culture. Our post on internship etiquette is a good place to start.

Your first day and first week

First impressions are mostly about small things. Arrive a little early, smile, learn names and bring a notebook.

• Introduce yourself to the people near you and ask what each person does.
• Ask your supervisor what a good first week looks like and how they like to communicate.
• Find out the working hours, break times and who to tell if you are sick or running late.
• Watch how people dress, speak to each other and take lunch. Then do the same.
• Write down instructions. Nobody minds a question the first time, but repeating one can be frustrating.

The dos

• Be punctual and reliable. Do what you said you would do, by the time you said you would do it.
• Show initiative. Finish your task, then ask what is next. Say yes to new opportunities when you can.
• Ask questions. Ask early, and bring what you have already tried. It shows you are thinking.
• Ask for feedback. A short check-in each week is enough. Ask what you should keep doing and what to change.
• Build relationships. Talk to people outside your team. Colleagues remember interns who are friendly and curious.
• Keep a log. Note what you did, what you learned and any results. It helps with your CV and with interviews later.

The don'ts

• Don't stay stuck. If you have been blocked for a while, ask for help. Silence causes more problems than questions.
• Don't ignore office culture. Every workplace has its own pace, tone and habits. Adapt to them.
• Don't procrastinate. Break work into small steps and tell people early if a deadline is at risk.
• Don't overstep. Respect roles and the chain of decisions. Offer help, but wait to be invited into work that is not yours.
• Don't leave tasks half done. If you cannot finish something, explain where it stands and what is left.
• Don't gossip. Be kind about colleagues, even in private chats.

When there is no work, you make a mistake or you get feedback

If you have no work

It happens, especially in small teams. Do not wait quietly. Tell your supervisor you have time and ask where you can help. Offer to support a colleague, research a topic for the team, or improve a document or process. Our guide to what to do when you lack work at an internship goes into more detail.

If you make a mistake

Everyone does. Tell your supervisor as soon as you notice, explain what happened in a few clear sentences and suggest a fix. Then note what you will do differently. Honesty builds trust. Hiding an error does the opposite.

If you get feedback

Listen without interrupting and say thank you. Ask for an example if something is unclear. Feedback is about the work, not about you. Pick one or two points to act on right away, and show the change in your next task. If you feel upset, take a moment before you reply.

Working with your supervisor

Your supervisor wants you to do well. They are also busy, and some have never mentored anyone before. That is normal, so help them help you.

• Ask how they prefer to be updated: a quick chat, a message or a weekly meeting.
• Send questions in a batch rather than one at a time.
• When you ask something, bring a suggested answer.
• Share suggestions politely. Fresh eyes can be useful, and most teams welcome good ideas.
• Keep your emotions in check when things go wrong. A calm, practical reaction is remembered.
• Learn how colleagues from different backgrounds show agreement, disagreement and respect. Our post on different work cultures in Asia can help.

Extra tips if you intern abroad

Interning in another country adds a few things to think about.

• Learn local etiquette. Find out how people greet each other, such as a bow or a wai, and how they address seniors. Learn a few greetings and a few words of the language. Trying matters more than getting it perfect.
• Join after-work gatherings. In some places, such as South Korea, dinners or drinks with the team are a big part of bonding. You can join without drinking alcohol. Go for a while, be friendly and leave when it suits you.
• Pack with the climate in mind. Think about heat and rain, and bring work clothes that suit the office. Keep copies of your passport and visa documents, a power bank and basic medicine.
• Plan your weekends. Make a short list of places you want to see and things you want to try. You will do better at work if you rest and enjoy your time off.
• Know where to get help. Every AIP program includes 24/7 emergency support, and our team is based in Bangkok. See how AIP works for what happens before and after you arrive.

Finishing strong

The last two weeks shape how people remember you.

• Hand over your work clearly. Write a short summary of what you did and where the files are.
• Thank your supervisor and the people who helped you, in person if you can.
• Ask for feedback one last time, and ask whether they would be happy to give you a reference.
• Connect with colleagues on LinkedIn and add your internship, with a few real results. Our step-by-step LinkedIn guide shows how.
• If you would like a role there, say so politely and early. Our post on asking for a full-time position after an internship has tips.

An internship is a stepping stone and a place to learn. Even if it does not lead to a job, the skills and contacts stay with you.

FAQs

What are the most important internship dos and don'ts?

Do arrive on time, ask questions early, finish what you start and ask for feedback. Don't guess when you are unsure, ignore the office culture, or go quiet when you have nothing to do. Reliability and a good attitude matter more than knowing everything.

What should I do if I have no work at my internship?

Tell your supervisor you have capacity and ask what would help most. Offer to support a colleague, tidy a process, or research something the team needs. Keep a list of small useful tasks so you are never waiting to be told.

How do I handle a mistake at work?

Tell your supervisor as soon as you notice it, say what happened in plain words, and suggest how to fix it. Stay calm, fix it, and note what you will do differently. Most supervisors respect honesty far more than a hidden error.

What if my supervisor seems too busy to guide me?

Many supervisors are new to mentoring and are juggling their own work. Book a short, regular check-in, send questions in a batch, and bring a suggested answer. Make it easy for them to help you.

How do I turn my internship into a reference or a job offer?

Do reliable work, ask for feedback along the way and keep a record of what you achieved. In your last weeks, ask your supervisor for a reference and connect with colleagues on LinkedIn. If you want a role, say so politely and early.
