What not to do when you're hiring

13 min readUpdated Written for Australian employers

There is a particular kind of hiring failure that does not look like a failure. The role gets filled. Nobody is sacked. And yet the business spent four months, the owner interviewed eleven people, two good candidates went elsewhere mid-process, and the person who started is the third choice.

Almost all of it is avoidable, and almost none of it is about effort. These are the fourteen mistakes that do the most damage to Australian SMEs, in rough order of how much they cost.

The short version

  • The most expensive mistake is slowness. Good candidates are off the market in two to three weeks.
  • Hiring only when desperate guarantees you choose from whoever is available, not whoever is good.
  • Vague ads generate volume, not quality — and volume is what makes the process slow.
  • Interviewing without a fixed set of questions makes it impossible to compare candidates, and legally harder to defend.
  • Most bad hires are visible in the first fortnight. Few businesses act then.

Taking too long to decide on a candidate

Strong candidates are typically off the market within two to three weeks of starting to look, so a process that takes six weeks is competing for whoever is left.

This is the single most expensive mistake on the page and the one business owners are least likely to recognise, because the delays all feel reasonable in isolation. Two weeks to collect applications. A week until the owner has a free afternoon. A second interview the following Tuesday. A fortnight on references and a decision.

From the candidate's side that is seven weeks of silence punctuated by two meetings. They accepted something else in week three.

Don't

Reviewing applications when the role closes

Instead

Review daily and interview the strong ones immediately. Good applications arrive in the first 72 hours.

Don't

Three rounds of interviews for a $70k role

Instead

Two, maximum — and for most SME roles, one proper interview plus a trial task.

Don't

Waiting to see 'the full field' before talking to anyone

Instead

Talk to the first genuinely strong applicant within 48 hours. You can still see the field.

Only hiring when you're already desperate

Hiring that starts after someone resigns or the workload breaks means you choose from whoever is available in that four-week window, rather than from the best people in your area.

Reactive hiring systematically selects for availability over quality. The best person for your warehouse role is currently employed and not looking. You will only ever reach them if you are visible before you need them.

This is why keeping a standing talent pool matters more for small businesses than for large ones — you hire less often, so each hire carries more weight, and you have no recruitment team to compress the timeline.

  • Keep the details of every runner-up. The second-best candidate from eight months ago is your fastest hire today.
  • Tell good applicants you did not hire that you will come back to them — then actually do.
  • Keep a careers page live even with no vacancies, so speculative applications have somewhere to land.

Writing the job ad as a position description

A position description is written for the person who already has the job. A job ad is written for a stranger deciding whether to care, and the two cannot be the same document.

Posting an internal document publicly is the most common cause of low applicant numbers in Australian small business hiring. It produces ads that open with the company's founding year, list twelve requirements, describe duties in verbs nobody uses out loud, and never mention pay.

The full fix is in how to write a job ad that gets applications. The short version: lead with the role, the pay, the hours and the suburb; cut the requirements list to what you would actually reject someone for; describe a real Tuesday rather than a set of responsibilities.

Hiding the salary in the job ad

Omitting pay reduces applications and attracts less suitable candidates, because the people with options filter out ads that will not say what the job pays.

"Salary commensurate with experience" is read by every candidate as less than I want. "Attractive package" is read as there is no package. The gap you are protecting in negotiation is smaller than the gap it creates in your applicant pool.

There is a second cost that is easy to miss: unsalaried ads waste your time. You will interview people whose expectations are $20k above your budget and discover it in minute forty.

Interviewing without a structure

Unstructured interviews measure rapport rather than capability, make candidates impossible to compare, and are harder to defend if a decision is ever challenged.

The default SME interview is a friendly conversation that wanders. The owner finishes with a feeling. That feeling correlates strongly with how similar the candidate is to the owner, and weakly with how well they will do the job.

The minimum viable structure

  1. 1

    Pick five questions before you meet anyone

    The same five, in the same order, for every candidate. Four about work they have actually done, one about why this role.

  2. 2

    Score each answer immediately

    One to five, written down before the next question. Memory reorders itself in favour of whoever you liked.

  3. 3

    Add a short, paid, real task

    An hour of the actual work beats an hour of talking about the actual work. Pay for it.

  4. 4

    Compare scores, not impressions

    If your scores and your gut disagree, that is worth examining rather than overriding.

Hiring for likeability instead of capability

"Culture fit" in practice usually means similarity to the interviewer, which narrows your team's range of skills and increases legal exposure without improving performance.

This matters more in small businesses, not less. In a team of nine, one hire shifts the composition meaningfully — and the instinct to hire people who feel easy compounds fast.

Don't

"Would I have a beer with them?"

Instead

"Can they do the work, and will they work well with the four specific people they'll sit with?"

Don't

Screening for 'culture fit' as a general vibe

Instead

Name the two or three behaviours you actually need — turns up on time, says when something's wrong, finishes things — and ask about those.

Don't

Ruling someone out because they're 'not what we usually hire'

Instead

Ask what specifically would stop them succeeding. If you can't name it, it isn't a reason.

Skipping the reference check

Two ten-minute calls to former managers surface more about how someone works than an extra interview round, and most small businesses skip them because the hire already feels decided.

The useful reference call is short and specific. Skip "what were their strengths" — nobody answers that honestly. Ask instead:

  • "What did they own, and what did you still have to check?"
  • "What would you have them do more of, and less of?"
  • "Would you hire them again, into what?"

The third question's hesitation is the data. A pause before "yes, absolutely" is worth more than the answer.

Writing a job ad that could be unlawful

A job ad that specifies or implies a preference based on a protected attribute can breach Australian anti-discrimination law, even when no discrimination was intended.

Most of these are accidental and come from describing the person pictured rather than the work required.

Ghosting the people you don't hire

Not replying to applicants costs you the talent pool you will need for your next vacancy, and in a local market it costs you reputation you cannot buy back.

A small business hiring in one suburb is not an anonymous employer. The 40 people you did not reply to include future customers, future applicants, and people who will be asked about you.

A two-line rejection sent promptly is remembered positively. It takes a template and ten minutes.

Treating onboarding as paperwork

Most of the risk in a new hire is resolved or realised in the first fortnight, and a first day that consists of forms and a desk is the most common reason a good hire looks like a bad one.

The cost of replacing someone who leaves in month three is close to the full cost of the original hire. Protecting against it is cheap:

  1. 1Send everything administrative before day one, so day one is about the work.
  2. 2Give them one real, finishable task in week one. Competence feels better than welcome.
  3. 3Name the person they should ask dumb questions. Nominate them, don't hope.
  4. 4Have a deliberate conversation at day 10 and day 30. Ask what is unclear and what is harder than expected.

Ignoring what the first fortnight tells you

Most genuinely poor hires show clear signals within two weeks, but small businesses typically wait three to six months before acting, which multiplies the cost.

The reluctance is understandable — you just spent two months hiring, and admitting it went wrong is admitting the two months were wasted. But the two months are already gone. The question is only whether to add six more.

Act early and the options are good: a direct conversation, a change in scope, extra training, or a clean and early parting. Wait and the options narrow to one difficult conversation and a longer paper trail. Employment law obligations also tighten over time, so early is cheaper in every sense.

Posting the job once and hoping

A job ad's visibility decays within days, so a single post with no follow-up reaches only the people who happened to be searching that week.

Treat the post as the start, not the task. Share it to your own channels, send it directly to three people likely to know someone, put it on your careers page, and refresh or re-post if the first week is thin. For how the main Australian boards differ in reach and cost, see the job boards guide.

Over-indexing on the résumé

A résumé shows where someone has been, not how well they did it, and screening heavily on it filters out capable people with unconventional histories.

This is particularly costly for SMEs, who cannot compete for conventionally impressive CVs and win mostly by spotting people slightly before the market does. Career changers, returners, people with a gap year, people from a different industry doing the same underlying work — this is where small businesses have an edge, and résumé-first screening throws it away.

A short work sample is the antidote. Thirty minutes of real work tells you more than three pages of history.

Not knowing what the hire actually costs

Businesses that only count the advertising cost tend to under-invest in the parts of hiring that matter, because the real expense is the owner's time and the weeks the role sits empty.

Advertising is typically a small fraction of what a hire costs an Australian SME. The large items are the owner's hours, lost productivity while the seat is empty, and the cost of getting it wrong. Working the real number out changes decisions — see what hiring actually costs, or run your own figures through the cost-of-hire calculator.

Common questions

What is the most expensive hiring mistake for a small business?

Moving too slowly. Strong candidates are generally off the market within two to three weeks, so a process that takes six weeks is choosing from whoever is left rather than from the best available people. It costs more than a bad ad, and it is far cheaper to fix.

Why am I getting no applications for my job ad?

In order of likelihood: the title is not what candidates search for, there is no salary, the requirements list is too long, the opening paragraph is about your company rather than the role, or applying takes too many steps. All five are fixable in an hour.

Why am I getting lots of applications but no good ones?

Usually because the ad is vague about the work and silent on pay, which maximises volume and minimises self-selection. Add a pay range, describe the day-to-day in specifics with real numbers, and ask one screening question only a genuine candidate could answer.

How quickly should I respond to applicants?

Within 48 hours for anyone you want to talk to, and within a week for everyone else. Speed is a competitive advantage that costs nothing, and in a local market the applicants you reject are part of your reputation.
