Final-year internship: carrying a project through to graduation and beyond

An internship that concludes the course

The final-year internship is the last practical experience before the degree is awarded. It is found mainly in master's programmes, engineering schools, business schools and some professional bachelor's degrees. Its length ranges from four to six months, the latter being the usual ceiling with the same organisation in one academic year.

Unlike a discovery internship, it is expected to produce a result: a study, a tool, a prototype, an analysis or an action plan. It feeds the dissertation or final report, which is sometimes marked and defended in front of a panel made up of teachers and the supervisor. Your institution remains the first point of contact for dates and validation criteria.

A timetable to build backwards

The search often starts in the autumn for a spring start. The more selective the degree, the earlier large companies recruit, sometimes several months before the start date. To avoid being caught out, work back from the date of your defence.

1. Get the deadline for handing in the dissertation and the date of the defence from your institution.
2. Count the four or six months of attendance and move the start date back accordingly.
3. Allow two to three months for applications, interviews and signing the agreement.
4. Keep a margin for holidays, bank holidays and any week set aside to prepare the defence.

This backward plan shows when the search must really begin and why leaving it to the last moment narrows your choice.

Choosing a topic you can finish

A good final-year topic fits in one sentence and has a clear scope. "Improving logistics" is too broad. "Measuring delivery delays at two warehouses and proposing three ways to reduce them" is a topic you can defend. Before accepting, ask simple questions: what data will be available, who can answer your requests, what deliverables are expected, by when, and who will approve the result.

Check too that it fits your degree. A panel expects the assignment to draw on the teaching of your speciality, not just to be a heavy workload. If the project is partly confidential, ask how the report will be written, or even restricted, without preventing the student from defending it.

Applying with a project rather than just a CV

Recruiters receive many similar applications. Yours stands out when it shows you understand what the organisation does and propose an angle for your contribution. The CV highlights course projects, earlier internships and the tools you master. The cover letter explains in a few paragraphs why this department, this topic and this period.

Employers advertise internships on their career portals, on institutions' platforms and at recruitment fairs. Speculative applications work better when they target a specific department and an identifiable need. Prepare for the classic interview questions: why this topic, which method, how you would organise the first six weeks, and what you would do if the data were missing.

Agreement, stipend and status

Like any internship, this one rests on an agreement signed by the student, the host organisation and the institution before the first day. It fixes the dates, the topic, the hours, the supervision and the follow-up arrangements. The intern is not an employee: they must not fill a permanent post in place of a staff member.

In France, once attendance exceeds two months in the year, meaning 44 days or 309 hours, a stipend is compulsory. Under the rules in force in 2026, the legal minimum is 4.50 euros per hour, and many employers pay more, notably in large groups or some sectors. Over a six-month internship the gap between this minimum and a higher payment is significant, so ask the question at the interview, not after you have signed.

During the internship: showing progressive results

The beginning is for understanding the organisation, the issues and the people. In the second month, a first diagnosis or review of the current situation is useful. The middle of the internship is when the main work gets produced. The last weeks are for consolidating, documenting, training a colleague to use what you have delivered and presenting the results.

• Set a regular meeting with your supervisor, even a short one.
• Keep a logbook that will feed the dissertation.
• Have each deliverable approved before sharing it more widely.
• Keep a record of assumptions, sources and successive versions.

A progress meeting with your supervising teacher around the halfway point lets you check that the topic still meets the requirements of the degree.

An illustration: a master's in data

Take a second-year master's student in data analysis on a six-month internship at a transport company. The figures are hypothetical and serve only to show the scale of effort. The topic: forecasting passenger numbers on three lines to adjust weekend timetables.

The first month goes on getting access to the data, understanding the business and defining the indicator. Months two and three are used to build a first model and compare it with the current method. Month four is for testing the model on a recent period and discussing the gaps with the operations managers. Months five and six are shared between documentation, presenting to management and writing the dissertation. At the end, the student has a documented tool, a report and written feedback from the supervisor.

Dissertation and defence

The dissertation generally follows a stable structure: context, research question, method, results, discussion, limits and recommendations. Write as you go rather than in the last weeks, because details are quickly forgotten. The defence often lasts twenty to thirty minutes of presentation followed by questions; pitch the technical level for a panel of specialists and non-specialists.

Prepare three key messages, two or three readable diagrams and an answer to the predictable questions: what was difficult, what could be improved, what did not work. Panels value clear-sightedness about limits more than excessive confidence.

Preparing what comes next without assuming a job

A final-year internship is sometimes followed by a contract offer, but this is never automatic and no rule requires it of the employer. It is better to raise the subject openly with your supervisor from the third or fourth month: are there open posts, what profile is wanted, what is the decision timetable?

At the same time, keep answering job advertisements, update your online profile with what you achieved during the internship and ask for a recommendation or an introduction. Even without a post, the experience provides concrete examples for later interviews. After graduation, support schemes for young graduates take over.
