How do you hire well in a small business?
By being specific about what the person will actually do, and by testing for it — because small businesses feel each hiring mistake far more sharply than large ones, where a poor hire can be absorbed.
Before advertising:
Write down what the first six months look like — the actual tasks and the outcomes you need. If you cannot, you are not ready to hire, and this exercise frequently reveals that you need a contractor, an agency or a process change instead.
Decide what is genuinely essential, which is usually a short list.
Set the salary and publish it. Not doing so wastes everyone's time and narrows the field to confident negotiators.
In the process:
Use a work sample. The single best predictor of performance is a realistic sample of the actual work — a short exercise, a paid trial task, a real problem discussed. Interviews alone predict performance poorly, and unstructured interviews predict it worst.
Structure the interview. The same questions to every candidate, scored against agreed criteria, which improves accuracy and reduces bias substantially.
Ask about specific past behaviour, not hypotheticals — "tell me about a time" beats "what would you do".
Pay for substantial exercises. Asking for a day of unpaid work is both unfair and self-defeating, since the strongest candidates decline.
Take references properly, and ask specific questions rather than for a general impression.
What small businesses get wrong: hiring someone like themselves; hiring for potential without capacity to develop anyone; over-indexing on enthusiasm; hiring too late, in a panic, which guarantees a rushed decision; and hiring a generalist when the need is a specialist, or the reverse.
Be honest about the offer. A small business cannot compete on salary or security, and can offer breadth, autonomy, proximity to decisions and visible impact. Say so plainly, and do not oversell stability you cannot guarantee.
Get the onboarding right. The first fortnight determines whether a good hire becomes a good employee, and it is what small businesses most reliably neglect.
Do the legal basics before the start date — contract, right to work, payroll, insurance and pension.
