The cost of a bad hire.
A bad hire is one of the most expensive mistakes in business — and largely preventable with structure. Gut-feel hiring is the culprit: it feels fast, it rarely is. This is the working kit: the business case, the data, how to hire for fit, and how to roll it out. Free to read. Yours to forward.
Size it for your teamGut-feel hiring is expensive. Structure is the fix.
The cost of a mis-hire doesn't show up as a line item — it's buried in wasted salary, a do-over recruitment cycle, and the six months of momentum your team lost while everyone waited for the obvious.
The US Department of Labor puts a bad hire's cost at up to 30% of first-year earnings. SHRM puts the average direct cost above $15,000 before you count team drag and manager time. Neither figure includes the opportunity cost of the role sitting half-filled.
The cause is almost always the same: hiring on gut feel instead of evidence. Unstructured interviews are notoriously unreliable predictors of job performance — interviewers decide in the first few minutes and spend the rest confirming it. A structured process takes the same time and doubles the signal.

Six findings worth quoting in the room.
Drawn from US DoL, SHRM, and structured-hiring research including Google's re:Work programme. Use them to open the conversation.
- Up to 30%
- The US Department of Labor estimates a bad hire costs up to 30% of that employee's first-year salary in direct costs alone — before team drag and management time are added.
- Half the manager's week
- Managers of underperforming hires report spending up to 17% of their working time — nearly a day a week — managing the situation instead of leading their team.
- It spreads
- A poor fit doesn't just underperform; it lowers the bar around them. Teams with one disengaged mis-hire show measurably lower morale and productivity within three months.
- Interviews mislead
- Unstructured interviews predict job performance only marginally better than chance. Interviewers typically make up their mind in the first few minutes and spend the rest confirming the impression.
- Structure doubles the signal
- Structured interviews — same questions, scored against a defined rubric — are roughly twice as predictive of performance as unstructured ones. Google's re:Work research confirms this at scale.
- Speed vs. rigour is a false trade
- Teams that skip structure to move faster consistently take longer end-to-end once the bad hire, the exit and the re-hire are counted. A structured process adds days, not weeks.
Size the cost.
Four inputs. The annual cost of mis-hires across wasted salary, replacement recruiting, and team drag — sized for your organization specifically.
Four moves that separate signal from noise.
Structure isn't slower — it's what makes fast hiring sustainable. These are the four things high-quality hiring teams do consistently.
Define the scorecard first
Write down exactly what good looks like before you post the role. The scorecard — competencies, outcomes, deal-breakers — is what keeps the hiring team honest and aligned.
- List 3–5 competencies that actually predict success in this role
- Define what 'strong' looks like for each one before interviews start
- Share the scorecard with every interviewer before the first call
Structure the interview
Same questions, same order, scored against the same rubric. Remove the variables that introduce bias and the signal improves immediately.
- Write behavioural questions tied to each scorecard competency
- Use a 1–5 scale with anchored descriptions, not a thumbs up/down
- No 'culture fit' gut calls — score on evidence, discuss after
Check references properly
Reference checks done well are one of the highest-signal steps in the process. Most teams treat them as a formality — which is why they get nothing useful out of them.
- Ask the same structured questions you'd ask in the interview
- Probe specifically: 'What would [name] tell you they need to work on?'
- Weight references from direct managers above all others
Decide on evidence, not vibes
Debrief as a structured discussion, not a vote. Each interviewer scores independently first, then you reconcile — that order matters. It stops the loudest voice in the room winning.
- Independent scoring before group debrief — always
- Flag and name any 'I just got a good feeling' reasoning
- Hire against the scorecard, pass on candidates who miss it
From a checklist to a repeatable hiring system.
Structure only works if it's the default, not the exception. Four steps to make it stick across every team and every hire.
- 01
Audit your last ten hires
Rate each one against their original scorecard. Where the process was loosest, the outcomes are worst. That's your starting point.
- 02
Build the scorecard library
Create a standard template for your most common roles and make it the first thing a hiring manager touches — before they open a job req.
- 03
Train the interviewers
A two-hour session on behavioural interviewing and calibration is enough to meaningfully lift interview quality. Make it mandatory for anyone on a hiring panel.
- 04
Measure quality of hire
Track 90-day performance ratings, manager satisfaction and retention at 12 months. Feed those numbers back into the scorecard so every cohort is better than the last.

Starting points for the four structured-hiring artefacts that matter most. Fill in the brackets and you're ready to run.
“Role: [title]. Outcomes: [what success looks like at 90 days]. Competencies: [3–5 behaviours that predict success]. Deal-breakers: [non-negotiables]. Scoring: 1 = no evidence, 3 = meets bar, 5 = exceptional — score each competency independently before debrief.”
“For competency [behaviour]: 'Tell me about a time you [situation]. What did you do specifically, and what was the outcome?' — then probe: 'What would you do differently?' Score on evidence: a 5 requires a concrete example with a measurable result.”
“For [candidate name], former [manager/peer] at [company]: 'In what context did you work together? What are their two or three greatest strengths? What would they say they're still working on? On a scale of 1–10, how likely are you to rehire them — and what's behind that number?'”
“Manager to new hire at day 30: 'What's been clearer than you expected? What's been harder? Where do you feel most uncertain about what good looks like? What do you need from me to hit your 90-day outcomes?' — Flag any misalignment now, not at month eight.”
