Hiring the right people is one of the most important decisions any business makes. A great hire can transform a team, while the wrong one will undoubtedly cost you time and money and affect morale. Unfortunately, not everyone is completely honest during the hiring process. Some exaggerate achievements, stretch timelines, or even fabricate entire experiences.
And the data suggests this is more common than many hiring managers realise. Research shows that 75% of HR managers have caught a lie on a CV, and around 85% of employers report discovering some form of misrepresentation during the hiring process.
While most candidates present themselves in the best possible light, certain warning signs may indicate a candidate isn’t being fully truthful. Recognising these can help you make better hiring decisions.
1. Their story keeps changing
One of the most obvious signs is inconsistency. If a candidate gives different versions of the same story at different stages of the interview process, it could be a red flag.
For example, their responsibilities in a previous role may sound impressive during the first interview but become vague or slightly different in later conversations. Small details changing over time can indicate the story isn’t grounded in reality.
2. Their achievements sound too good to be true
Candidates often highlight their successes, but if every story positions them as the sole hero who delivered record-breaking results time and time again, it may be worth probing deeper.
Real work environments involve collaboration, challenges, and failure. A candidate who claims flawless success in everything they touch may be over exaggerating their achievements.
3. They struggle with details
When someone is recalling a genuine experience, they can usually describe the situation clearly, what the problem was, how they approached it, and what the outcome was.
Candidates who are being generous with the truth will struggle with specifics and give overly general answers or avoid technical details.
Research also shows that the most common CV fast ones involve inflated skill sets (around 57%), exaggerated responsibilities (55%), and manipulated employment dates (42%).
4. Body language doesn’t match the story
Body language can sometimes reveal discomfort. Signs such as avoiding eye contact, frequent pauses, over explaining, or appearing defensive when questioned may indicate the candidate is not confident in their answers.
However, nerves can also cause similar behaviour, especially during interviews.
5. Their CV doesn’t align with their skills
Sometimes a candidate’s CV may list skills, specific knowledge, or responsibilities that they struggle to explain in depth during the interview.
For example, someone claiming extensive experience with a specific skill set may not be able to explain how they used it in real-life scenarios.
Surveys suggest that 60% of candidates admit to exaggerating their skills on their CV.
6. They avoid reference checks
Candidates who hesitate to provide references or give vague contact details could be trying to prevent you from verifying their claims.
While there can be legitimate reasons for this (such as confidentiality), it’s always worth investigating further, as a reference is invaluable.
7. Their historical timeline doesn’t add up
Employment gaps are normal, but inconsistencies in dates, overlapping roles or unclear explanations for transitions may indicate a candidate is trying to hide something.
Interestingly, around one in four background checks reveal discrepancies between what candidates claim and verified records, highlighting how frequently timeline issues appear.
Final thoughts
Hiring isn’t just about spotting great candidates; it’s also about verifying authenticity.
The reality is that exaggeration and misrepresentation are far more common than most hirers realise. The aim of an interview shouldn’t be to catch someone out but to establish and understand the truth behind their experience.
Hiring managers can focus on three things:
1. Structured interviews that qualify every candidate with consistent, evidence-based questions
2. Dig deep and investigate real-life examples rather than surface-level claims
3. Verification, with reference checks and timeline validation
Genuine candidates will be able to explain their work history and skill set clearly, and those who can’t usually reveal the gaps themselves.
The best defence against dishonesty is curiosity, structured process, and verification. When those three are built into your interview process, the truth tends to surface naturally.
