Interview advice tends to stop at the final handshake, as if the process ends when the questions do. It does not. Between "we'd like to offer you the role" and your first day sits a stage with its own rules, its own paperwork, and several places where deals genuinely fall apart: references, background checks, offer terms, resignation, and the counter-offer conversation.
This guide walks through the whole sequence so nothing at this stage catches you off guard.
The sequence, start to finish
A typical UK process after a successful final interview runs:
- Verbal offer, usually by phone from the recruiter or hiring manager
- Negotiation, if you choose to negotiate (and you usually should at least test the terms)
- Written offer and contract, often conditional
- References and background checks
- Your resignation and notice period
- Possible counter-offer from your current employer
- Start date and onboarding
Timelines vary from days to months depending on the sector; regulated industries with heavy vetting sit at the slow end. Two structural points to hold onto throughout: first, most written offers are conditional (on references, right-to-work checks, sometimes qualifications or vetting) and the conditions are real; second, do not resign until the written offer is in your hands, however warm the phone call was. Verbal offers evaporate more often than people expect, through hiring freezes, budget changes, and simple internal chaos.
References: how they actually work
References cause more anxiety than they deserve, mostly because candidates imagine a former manager delivering a detailed verdict on their performance. The reality in the UK is usually tamer.
What most references contain. Many employers, especially larger ones, give factual references only: job title, dates of employment, sometimes reason for leaving. This is company policy designed to limit legal risk, not a comment on you. Employers requesting references know this and treat a factual reference as entirely normal.
What referees may not do. A referee is not obliged to provide a reference at all (with narrow exceptions in some regulated roles), but any reference given must be true, accurate, and fair. A knowingly misleading reference exposes the referee to legal risk in both directions, towards you and towards the new employer.
Choosing your referees. Where you have a choice, pick people who managed you recently and rate you, and always ask them before naming them. A warned referee responds quickly and speaks well; an ambushed one delays your start date. Brief them: tell them the role, what it emphasises, and what you would love them to mention if asked.
If you fear a bad reference. If you left somewhere on poor terms, do not simply hope. Options: nominate a different manager from the same employer, ask HR whether their policy is factual-only (it often is), and consider a second referee who will be warm. If a hostile reference actually derails an offer, take advice; you may have recourse if it was inaccurate or unfair.
Timing note. Referees are normally contacted only after you accept a conditional offer, not during interviews, and reputable employers will not contact your current employer before you have resigned without your explicit permission.
Background checks
Depending on sector, expect some combination of: right-to-work verification (universal), identity checks, employment history verification, criminal record checks (DBS in England and Wales, at the level the role legally justifies), credit and sanctions checks in financial services, and professional qualification verification.
Two pieces of practical advice. First, respond to document requests fast; vetting is the most common cause of delayed start dates, and the delay is usually the candidate's paperwork. Second, be truthful everywhere, including about grades and dates. Discrepancies discovered in vetting kill offers that interviews earned, and they are checked more often than people assume.
The offer itself: read before you sign
When the written offer arrives, read the whole thing, including the contract behind it. Check in particular:
- Money, completely. Base, bonus structure and whether it is discretionary, pension contributions, and anything promised verbally. If it was agreed on the phone, it should appear in writing. If it does not, ask, in writing, before signing.
- Probation terms and the notice period on both sides during and after probation.
- Restrictive covenants. Non-compete, non-solicitation, and garden leave clauses matter enormously later, at exactly the moment you cannot renegotiate them. Understand them now.
- Location, hybrid terms, and mobility clauses, especially any right to change your base location.
- Holiday, sick pay, and anything you specifically care about (sabbaticals, training budgets, professional memberships).
If you intend to negotiate, the window is between the verbal offer and your acceptance, and it is a normal, expected conversation when done professionally. Our guide to negotiating a job offer covers the scripts; the short version is: be warm, be specific, justify your ask with evidence, and get the result in writing.
Resigning well
Once the written offer is signed (and any conditions you are worried about are cleared), resign in writing, briefly and gracefully: you are resigning, your last day per your notice period, thanks for the opportunity. Hand it to your manager in person or by call where possible, before they hear it elsewhere.
Do not use your resignation to settle scores, whatever the temptation; your industry is smaller than it looks, and this employer may one day be your reference. If asked for an exit interview, be honest but measured. Then work your notice properly. Finishing well is remembered longer than almost anything else you did there.
The counter-offer conversation
If you are any good, there is a fair chance your employer responds to your resignation with a counter-offer: more money, a promotion promise, a new project. Decide your answer before you resign, because the moment is flattering and destabilising in equal measure.
Think it through honestly. Money was rarely the whole reason you looked. Whatever pushed you to interview (scope, progression, management, culture) usually survives a pay rise. The trust dynamics also shift after a resignation is withdrawn: you have told them you were leaving once, and both sides remember. Counter-offers deserve consideration; they do not deserve automatic acceptance just because the number moved. If the new role was the right decision last week, it usually still is.
Between acceptance and day one
Keep momentum through the gap: confirm your start date in writing, stay responsive to onboarding requests, and keep gentle contact with your new manager, especially over a long notice period. If your start is months away, a short message every few weeks keeps you visible and signals the enthusiasm they hired. And if something material changes on either side, surface it early rather than hoping.
The follow-up habits that served you during the process still apply here; our guide to following up after an interview covers the tone that works.
And if the offer never comes
Sometimes the final stage is a rejection, or silence. Chase once, politely, after the stated decision date; ask for feedback if declined; and treat anything you learn as preparation for the next process. The candidates who convert their next final round are usually the ones who found out why they missed this one.
