From Internship to Full-Time: Working Towards a Return Offer

Some employers link graduate recruitment to summer or term-time internships. Students with strong internship performance may receive an offer for a full-time role, often called a return offer. For mainland students studying in Hong Kong, an internship is also a first formal assessment in the local workplace. This guide covers what to do before, during and at the end of an internship, along with visa and compliance points. See Batch 1, no. 20, for the rules on internships during study for non-local students.

1. Confirm that the internship is permitted

1. During study, the work restrictions and exemptions for non-local students depend on the conditions of the No Objection Letter (NOL) issued by the Immigration Department. HKUST’s student guidance summarises a temporary exemption from part-time work restrictions for full-time non-local undergraduate and postgraduate students. CUHK’s materials for non-local students also remind them to hold a valid NOL and follow university rules on full-time work during term.
2. If the internship is under the Innovation and Technology Commission’s STEM Internship Scheme, its official guidance says non-local students may intern only in Hong Kong and must meet the conditions on their visa or entry permit. The internship must be full-time and last at least 28 calendar days. Each university sets its own allowance arrangements.
3. After graduation, you generally need IANG or another work visa before starting a full-time job. CUHK’s career-centre material reminds recent graduates to wait for formal approval from the Immigration Department before starting work. See Batch 1, nos. 1 and 2, for visa rules.

2. Before the internship starts

1. Find out how you will be assessed. Ask HR or your supervisor who evaluates you at the end, what they assess, whether there is a mid-term review and whether you will give a final presentation.
2. Ask how a return offer works and who usually decides. Do not assume every internship has a full-time vacancy.
3. Build the basic skills the role requires, such as Excel, a programming language or an internal data tool, until you can use them at a practical level.
4. Learn about the team from public information: what business it works on and whom it serves.

3. The first two weeks

1. Arrange a short alignment meeting with your supervisor. Ask about your main tasks, how success will be measured and how often they want progress updates.
2. Write down what they say and send a short email to confirm. This aligns expectations and gives you a reference point for the later review.
3. Get to know the team. Introduce yourself to your supervisor, colleagues and contacts in partner teams.
4. Learn the rules on confidentiality, information security, personal trading (in financial institutions), dress and attendance. A compliance breach is more serious than working slowly.

4. How to do good work through the middle of the internship

1. When you take on a task, repeat the requirements and confirm the deliverable and deadline.
2. Before submitting, check the figures, required format and spelling. Small errors are a common way interns lose marks.
3. Do not let a blocker linger. Try a reasonable approach yourself, then bring your attempt and a specific question to your supervisor.
4. Send your supervisor a short weekly update: what you completed, what problems you faced and what you plan to do next week.
5. Ask for feedback proactively. Midway through, ask, “What am I doing well, and what is the most important thing I should improve?” Then show the improvement in your work.
6. Offer to take on additional work, but do not overstep. First make sure your assigned work is done well.
7. Keep a record of projects completed, problems solved and feedback received. These are material for your CV and interviews.

5. Relationships and communication

1. A Hong Kong team may use Cantonese, English and Mandarin. If you do not understand, politely ask the speaker to rephrase; do not pretend you understood.
2. In meetings, listen first, check your understanding and then ask a question or share an idea.
3. Join team social activities while maintaining professional boundaries.
4. Do not criticise colleagues, other teams or other companies.

6. Final presentation and assessment

1. Many internship programmes end with a presentation about your project. See no. 9 in this batch for preparation.
2. Cover the project background, your contribution, the result, what you learned and what you would improve if you continued.
3. Describe the result accurately. Do not overstate your personal contribution to a team outcome.
4. There may be a return-offer interview focused on your internship performance and understanding of the full-time role. Prepare behavioural answers using examples from your internship.

7. At the end of the internship

1. Ask how and when you will hear the outcome of any return-offer decision.
2. Say goodbye to your supervisor and key colleagues, and thank them for specific help.
3. Hand over clearly: organise files, progress and unfinished tasks for the team.
4. Keep in touch afterwards, for example on LinkedIn; see Batch 2, no. 18.

8. If you receive a return offer

1. Read the offer terms carefully; see Batch 1, no. 17.
2. Check the response deadline. The US National Association of Colleges and Employers (NACE), in an advisory opinion on reasonable deadlines, notes that employers may give students who have completed summer internships anywhere from two weeks to as long as two months to consider a full-time offer, depending on the business and number of candidates. Hong Kong employers vary; follow the deadline in your offer. If you need more time, see no. 15 in this batch.
3. After accepting, prepare your visa application as required by the Immigration Department. See Batch 1, no. 9, for the part the employer must complete.
4. Do not accept another offer after accepting this one. See no. 16 in this batch for the consequences of reneging.

9. If you do not receive a return offer

1. Ask politely why and request feedback; see no. 13 in this batch.
2. Separate the reason from your performance. The employer may have limited places or changed business plans, which does not necessarily mean your work was poor.
3. If your supervisor was satisfied with your work, ask whether they would be willing to act as a referee for future applications. Get their permission first.
4. Put the internship on your CV, emphasising measurable results and skills learned.
5. Use your industry knowledge from the internship to apply to other employers in the same sector.
