How to avoid a bad hire
How do I avoid making a bad hire?
The most reliable way to avoid a bad hire is to decide what the role and your business genuinely need before you look at a single CV, then assess every candidate against those same criteria using the same structured questions. Bad hires most often come from gut-feel decisions and inconsistent interviews.
Most bad hires aren't caused by bad candidates. They're caused by a process that couldn't tell the difference.
Why do new hires leave in the first few months?
New hires most often leave early because the role or the working culture turned out different from what they expected. Mismatched expectations, a poor fit with how the business actually operates, and weak onboarding are the most common causes, and all three can be reduced before the hire is made.
Being honest in the job advert and the interview about how the business really works is one of the simplest ways to reduce early leavers.
What are the warning signs of a bad hire during interviews?
Common warning signs include vague answers that avoid specific examples, blaming previous employers for every problem, a mismatch between their CV and what they describe, little interest in how your business actually works, and answers that change depending on how the question is framed.
Warning signs are far easier to spot when every candidate answers the same questions, because you can compare like with like.
How can I tell if a candidate is just telling me what I want to hear?
Ask questions that force a trade-off between two reasonable options rather than questions with an obvious right answer. When candidates must choose between competing priorities, such as speed versus accuracy, their answers reveal how they actually work instead of what they think you want.
“Are you a team player?” invites a rehearsed yes. “Would you rather finish a task alone quickly or slowly with the team's input?” doesn't.
Is gut feeling a good way to hire?
No. Research on personnel selection consistently shows that unstructured, gut-feel interviews predict job performance less accurately than structured methods. Gut feeling is heavily influenced by first impressions, similarity to the interviewer, and confidence, none of which reliably indicate how someone will actually perform.
Instinct still has a place, but it works best as one input alongside consistent evidence, not as the deciding factor.
How many people should I interview for one role?
Most small businesses interview three to six shortlisted candidates for a role. Fewer than three gives you little to compare against; more than six usually means screening wasn't strong enough before the interview stage. A good shortlisting process matters more than a higher number of interviews.
If you're interviewing ten people for one role, the problem is usually the screening, not the candidate pool.
What should I do if a new hire isn't working out?
Address it early and directly. Set out clearly what isn't working, what good looks like, and a fair timescale to improve, ideally within the probation period. Waiting and hoping it resolves itself usually makes the situation more expensive and harder for everyone, including the employee.
For anything beyond an informal conversation, follow a fair process and take HR or legal advice.
