What is a summer internship?
A summer internship is a structured 8–10-week placement between June and August at an investment bank or, less commonly in France, a consulting firm. It involves real work and ongoing assessment, with both sides explicitly aiming for a permanent offer or a longer internship.
The format originated in English-speaking markets and provides a structured route into junior roles. In Paris, international banks offer summers, while many hires also come through longer or off-cycle internships. Check each institution’s actual opportunities rather than generalising by city.
The timetable: it starts a year ahead
Applications for a summer internship may open at the end of the previous summer. For example, Goldman Sachs announced 15 August 2026 as the opening date for its EMEA 2027 programme, with rolling review. Dates and selection methods vary by bank.
Prepare your CV, answers and technical foundations before your first target programme opens. For each bank, record the official date and check whether recruitment is rolling instead of relying on a generic timetable.
- August–October of the previous year: portals open and online applications begin, including CVs, letters and sometimes written questions.
- September–December of the previous year: online numerical and logic tests, HireVue or other recorded video interviews.
- October–February: interviews — HR screening, technical and fit rounds — then a superday or assessment centre.
- November–March: offers on a rolling basis.
- June–August: the internship itself, followed by the conversion decision.
The selection process, step by step
Initial screening is based on your CV: education, academic results, early experience and technical signals. Your application must be clear, and you should be able to discuss every detail in an interview.
Next come online tests — numerical and logical reasoning, sometimes behavioural games — and often a recorded video interview such as HireVue. Live interviews combine fit, such as “why M&A?” and “why this bank?”, with technical questions: accounting, EV-to-equity bridge, valuation, DCF and LBOs for finance; cases and market sizing for consulting. A superday brings several interviews with senior bankers or consultants into one day.
Conversion: the main goal of a summer internship
A summer internship can lead to an offer, with no guarantee. During the programme, you are assessed on execution quality, reliability, response to feedback and how you work with the team. JPMorganChase states that top-performing interns may receive an offer to continue.
Not converting is not the end of the road: the experience remains a strong signal when applying elsewhere for off-cycle or permanent roles. It is easier to respond early, so ask for feedback halfway through rather than discovering the outcome at the end.
Who can apply, and when should preparation start?
Summer programmes mainly target penultimate-year students: the first master’s year or a gap year in France, and penultimate year in the UK. Some accept final-year bachelor’s students. Spring weeks, usually early-degree insight programmes, provide an earlier route towards London summers.
Serious preparation starts three to six months before interviews: technical skills for banking, cases for consulting, a convincing motivation story and targeted networking. Speaking with an analyst in the target team before applying can distinguish two otherwise similar CVs.
A typical timeline for a 2027 summer internship
| Period | What happens | What you need to do |
|---|---|---|
| Before August 2026 | No official stage yet | Finalise your CV, select targets, start networking and practise technical questions or cases |
| Aug–Oct 2026 | Portals open | Apply early for rolling recruitment: early waves fill places |
| Sep–Dec 2026 | Online tests, HireVue | Practise numerical tests and recorded video interviews |
| Oct 2026–Feb 2027 | Interviews and superdays | Intensive mocks: technical questions + fit for M&A, cases + PEI for consulting |
| Nov 2026–Mar 2027 | Packages | Compare, negotiate where appropriate and confirm promptly |
| Jun–Aug 2027 | The internship | Aim for conversion: execution, attitude and halfway feedback |
Frequently asked questions
When should I apply for a 2027 summer internship?
As soon as your target programme opens if recruitment is rolling. For example, Goldman Sachs announced 15 August 2026 for its EMEA 2027 Summer Analyst programme. Check other schedules bank by bank.
Do I need a previous finance internship to secure a summer internship?
It is not a formal requirement, but it is a real advantage: an initial internship in transaction services, audit, corporate finance or a boutique strengthens your application. A finance society, quantitative project or documented personal investment activity can provide early signals instead.
Should I target summer or off-cycle internships?
Both, if your schedule allows. Summer internships are a common structured format in international offices; off-cycles are another important format in Paris. Requirements and durations vary by listing, though some preparation overlaps.
Do strategy consulting firms offer summer internships?
Structured summers are less common than in banking. In France, firms mainly recruit gap-year or final-year interns on a less rigid timetable. Some offices still offer summer internships or programmes; check each firm.
What is the conversion rate from a summer internship to an offer?
It varies by bank, year and team, and banks do not publish a reliable figure. Conversion consistently depends on execution, reliability and teamwork as well as technical skills. Prepare for a summer as a ten-week interview.
