Offers: the return offer, the deadline and the renege

The internship is an eight-to-ten-week interview¹

A return offer is a full-time job starting after graduation, made at the end of the internship. That is the point of the internship, and why the graduate application is the fallback.

It is not a formality¹

In some years more than half of interns have not received one. The market matters: when deal activity is poor, banks give few return offers whatever the interns did, and some boutiques never plan to bring interns back full-time at all. Ask at offer stage whether the programme is designed to convert.

What loses one¹

The avoidable reasons are soft skills - poor communication, off-colour remarks, seeming anti-social - and hard ones: careless Excel and PowerPoint, maths mistakes, not checking work.

Employers do think interns are better prepared²

In the Institute of Student Employers' 2025 survey, 77% of UK employers agreed that former interns are more work-ready. The same survey found 140 applications per graduate vacancy across all sectors and graduate vacancies down 8% - an internship is the less crowded door.

One to two weeks is routine³

Most routine offers carry a one-to-two-week deadline, according to the US careers-service association NACE, and months to decide is unusual. The exception is an intern's return offer, which employers often make early in their cycle to give their own interns priority.

The next bank will not speed up for you⁴

JPMorganChase says plainly that if you hold an offer from another company with a close deadline, it reviews applications on a rolling basis and cannot accelerate its decision. Plan the order you apply in with that in mind.

Ask for more time, in writing³

Tell the employer your situation and when they will hear from you, and keep the exchange in writing. Be prepared for an extension to be refused.

The extreme case is an exploding offer^5,6

In US private equity's on-cycle process, offers from the first days usually explode on the spot; in January 2026 one candidate was asked to sign before leaving the building. Banking internships are rarely that abrupt, but it is where the calendar pressure in this industry ends up.

What it can cost⁷

Accepting an offer and then withdrawing can lose you both offers if the second falls through, damage the relationships that got you the first, and bring sanctions from your university's careers service, up to a ban from on-campus recruiting. Industry-wide blacklists do not seem to exist, and firms do not sue.

When it is easier to defend⁷

The case is strongest when the new offer is substantially better on firm, pay, team or location, when the start date is months or years away, and when the first offer came through an online application rather than people who vouched for you. Moving between two similar mid-market banks is the weak case.

Accept in good faith³

The careers-service advice runs the other way: accept an offer in good faith, without intending to renege later, and talk to the employer rather than disappearing. The honest position is to decide before signing, not after.

Some employers now write it into the job⁸

In 2025 JPMorgan told incoming analysts that accepting a future-dated offer from another firm within their first 18 months would end their employment, and other banks moved to regular attestations. An offer can carry obligations that start before the job does.

The routes that remain¹

Recruit for full-time roles at other banks, take an off-cycle or post-graduation internship - more common in Europe - do a master's in finance, or move to a neighbouring field such as equity research or corporate banking. None of these is unusual.

You will be asked why¹

The next interviewer will ask why you did not get a return offer. Tell the truth, briefly and without blaming anyone: what went wrong early, what you did about it, and - where it is true - that market conditions cut the number of offers.
