Job interviews are one of the most stressful parts of the hiring process. Candidates are expected to be confident, polished, and memorable — all within a short window. Under pressure, it’s not surprising that some people stretch the truth to improve their chances of landing the job.
But where do they draw the line between confidence and fabrication? And how can employers spot when someone isn’t being entirely honest?
A recent UK-wide survey found that 31.7% of job seekers have lied during a job interview. While some fibs are minor — like tweaking a job title — others can have serious consequences for employers and teams.

The most common lie? The reason for leaving a previous job. Many candidates feel uncomfortable admitting they were let go, left a poor environment, or had a negative experience — so they reframe the story to sound more professional or appealing.
Who’s Most Likely to Lie?
The study also revealed:
- 34% of women admitted to lying, compared to 29.3% of men
- 47.9% of job seekers aged 25–34 had lied in interviews
- London had the highest rate of dishonesty (39.8%), followed by the West Midlands (37.8%)
- The Southwest had the most honest job seekers, with only 22.7% admitting to lying
As recruitment tools and screening practices evolve, spotting these lies is becoming easier — but many still slip through the cracks.
How to Spot Dishonesty in Interviews
Lies can lead to hiring regret, team disruption, and wasted resources. Here are five tips to help identify red flags:
1. Look for inconsistencies
Cross-reference the CV, cover letter, and interview answers. Watch for mismatched dates, titles, or qualifications.
2. Ask behavioural-based questions
Request specific examples from the candidate’s past. It’s much harder to fabricate detailed stories on the spot than it is to answer hypotheticals.
3. Listen for vague language
If a candidate avoids specifics and relies on general statements — like “I worked well with others” — they might be stretching the truth.
4. Verify references and work history
Speaking to previous managers or colleagues is one of the most reliable ways to validate a candidate’s claims.
5. Set an open, honest tone
When candidates feel comfortable and not overly judged, they’re more likely to be transparent about past roles, gaps, or changes.
Final Thoughts
Job seekers often feel pressure to present themselves in the best possible light — but exaggerating experience or credentials can lead to poor hiring decisions. By understanding the most common lies and using structured interview techniques, recruiters can make more informed choices and build stronger, more reliable teams.
