Spring Weeks in London: the 2027 Timeline and How Offers Are Actually Decided

A spring week stopped being an insight programme years ago. On paper it is two to five days at a bank during the Easter break: workshops, shadowing, networking, a case study. In practice it is the front door to the summer internship, which is itself the front door to the graduate seat. If you are in your first year of a three-year degree, or your second year of a four-year one, this is the highest-leverage application you will make at university.

I sat on the hiring side of this system for fifteen years. This article gives you the 2027 timeline as it stands, and then the part most guides skip: what the bank is actually doing during your week, and how the conversion decision really gets made.

What a spring week is, and what it is not

What it is: an extended assessment. The programme content (the panels, the training sessions, the socials) is real, but its function is to let the bank watch a shortlist of first-years operate for a week. Strong performers are fast-tracked towards the following summer's internship, through end-of-week interviews, a case study, or a direct invitation to an assessment centre.

What it is not: a guarantee. Conversion varies enormously by bank, from a minority of the cohort at some houses to a substantial majority at others, and the variation is worth researching because it changes which offers you should prioritise. Completing a spring week and converting nothing still leaves you applying to summer internships through the front door with a strong CV line, which is a perfectly recoverable position.

Who is eligible

First year of a three-year degree, or second year of a four-year degree, so that the following summer is your penultimate one. Banks state graduation windows precisely in each posting; read them, because applying outside the window is an automatic rejection that also wastes your one application for the cycle at that bank.

Separately, most large banks run earlier diversity and access insight programmes with their own timelines. If you are eligible, register early; they often feed the same pipeline a step sooner.

The 2027 timeline, month by month

• Now to August 2026. Interest registration is already live at some banks for spring 2027, and the earliest applications open over the summer. This window is for getting ready: CV to standard, story built, aptitude test practice started, registrations filed.
• August to October 2026. The main wave of applications opens. Almost everything is rolling and effectively first come, first served: banks fill assessment slots as applications arrive, so an identical application submitted in week one and week six can meet different outcomes. Apply within the first two weeks of each opening.
• September to November 2026. Online assessments run as applications progress: numerical and logical tests, situational judgement, increasingly game-based formats, and recorded video interviews on platforms like HireVue.
• October 2026 to January 2027. Assessment centres and offers, still rolling. Some banks conclude before Christmas; others run into the new year.
• February 2027. Scheduling and logistics for offer holders.
• March to April 2027. The weeks themselves run over the Easter break.

Every bank moves its own dates, and they move year to year. Treat the pattern above as the map, check each portal for the territory, and build a simple tracker: bank, opening date, submitted date, stage, next action.

The application itself, stage by stage

The CV is screened first, as elimination rather than selection; thirty seconds, a scan for grades, brands and numbers. Get it to standard before the first application goes in, not after the third rejection.

Then competency questions: written versions of the classic fit questions, usually one to five of them at 150 to 300 words. Why banking, why this bank, a teamwork example, a challenge overcome. These are read, and generic answers pasted across ten banks read exactly like generic answers pasted across ten banks. Write once per question type, then genuinely tailor per bank.

Then tests, then video. The tests are learnable: little and often beats a panicked weekend, and practising the specific provider's format matters more than generic drilling. The video interview is your story and motivation questions delivered to a camera; rehearse with the camera, because the first three recorded attempts are always worse than people expect.

How conversion is actually decided

Here is the week from the other side of the table. From the first morning, people are noting names. Not formally, mostly: analysts mention who asked sharp questions, associates mention who faded by Thursday, and the graduate recruitment team collects it all. By the final day, when the case study or conversion interviews happen, a picture already exists.

What converts, in my experience of those conversations:

• Prepared, specific questions. “What does an analyst do day to day” is on the website. “How did your team's role change between signing and closing on the deal you mentioned” is a question from someone who was listening.
• Consistent energy across the whole week. The Thursday fade is real, visible and noted. Being the same person in the last session as the first is rarer than it should be.
• How you treat the other students. The week is full of group moments, and collaboration is being watched more closely than answers. The candidate who elbows peers aside to perform for seniors converts far less often than they think.
• Following up properly. Short, specific notes to the people you actually spoke with, referencing the actual conversation. Not a blast, not a template.

What kills: a phone out during sessions, monopolising every Q&A, skipping the social parts, and rudeness to anyone at all, including events staff. The final decision is a conversation in a room, and it centres on one question: would I want this person on my desk next summer. Everything you do during the week is evidence in that conversation.

What to do this term

• Get the CV to the screen standard now, before openings, not during them.
• Build your sixty-second story and your why-banking answer; the competency questions are their written form.
• Start aptitude test practice in short, regular sessions.
• Register interest everywhere relevant and check portals weekly from August.
• Begin alumni outreach: one good conversation before applications sharpens every written answer you will submit.
