Why does a recruiter ask about location, work authorisation and start date in a screening call?

### Why these three fields come first Of the roughly seven facts on a recruiter's intake checklist, three are eligibility gates rather than preferences: where you can work from, whether the employer can employ you for that country and entity, and when you could actually start. Each of them can end the process on its own, regardless of how strong an engineer you are. That is why they arrive early in a 25-minute call — clearing them at minute four is cheap, and discovering them at round four has already burned several engineers' hours. ### Location and work pattern An opening is normally anchored somewhere: a country and often a specific office, with an expected pattern such as on-site, hybrid with a stated number of office days, or remote inside a defined region. The anchor exists for reasons the recruiter cannot waive on a call — payroll entities, tax registration, on-call coverage windows, and in regulated industries, requirements about where certain work may be performed. So the recruiter is not asking where you would like to live. They are checking one fact against another fact. What this means for you is that vagueness is costly in both directions. 'I am flexible' reads as unresolved and leaves the field unfilled; an over-committal 'I can be anywhere' invites an offer built on an assumption you may not honour. The useful register is specific and bounded: name where you are based, name what you can commit to, and name what you cannot. ### Work authorisation This is the field that most needs care, from both sides. The shape of the check is simple — can this employer, in this country, employ this person for this opening, now and for its expected duration — but the substance is genuinely jurisdiction-dependent. Whether an employer sponsors at all, which openings they sponsor, how status transfers between employers, what timelines apply and even which questions a recruiter may ask vary by country, by employer policy and over time. Some markets also restrict what an employer may ask at this stage. Because of that variation, treat everything here as a shape rather than a rule. Nothing in this material is legal or immigration advice, and no general statement about visas or sponsorship should be relied on for your own case: confirm your specific status and options with a qualified professional or the relevant official source, and describe your situation to a recruiter in your own accurate terms. The practical guidance that survives every jurisdiction is narrow and worth following anyway: know your own status before the call, state it in one plain sentence, do not overstate it, and do not guess at timelines you have not verified. An inaccurate answer here is discovered later by a background or right-to-work check, and that discovery is far more damaging than the original constraint would have been. ### Start date The recruiter needs a date they can plan against. Your earliest realistic start is a function of things you can find out before the call: any notice period you owe, commitments you have made, and the lead time between an accepted offer and a first day, which in a regulated setting can be extended by background and screening checks the employer runs. Notice-period norms and their enforceability differ by country and contract, so state what your own agreement says rather than what you have heard is standard. ### A worked example A regulated payments company is hiring for a card-settlement team and the opening is anchored hybrid to one office, three days a week. On a 25-minute screen the recruiter reaches these fields at about minute four. One candidate, moving into engineering from another field, has checked her own situation beforehand: she names her city, confirms she can meet the three-day pattern, states her work-authorisation situation in one sentence, and gives a start date built on the notice her contract actually specifies. The whole block takes ninety seconds and the recruiter moves on. A second candidate improvises — 'probably a month, maybe sooner' — then emails a different date two days later and a third after speaking to his manager. Nothing he said was dishonest. But three versions of one fact turned a routine field into a reason for the recruiter to hedge in the write-up. ### The failure mode The damage on this leaf comes almost entirely from treating the call as small talk and improvising when the process facts are requested. These are the facts most likely to be improvised, because they feel administrative, and the most expensive to improvise, because they are verified later. Ten minutes of preparation — three sentences written down, each one you would be comfortable seeing quoted back to you in a written offer — removes the entire risk. ### When you genuinely do not know Saying so is a correct answer, provided it is bounded: name what you are checking, and name when you will come back with it. A recruiter can log 'confirming notice period, will send by Thursday' without friction. What they cannot use is a number that changes twice.
