Imagine you are hiring a sales manager.

“I rescued an entire division and increased revenue by 40%,” the candidate says.

You nod and make a note. Then you move to the next question.

But what if six people shared that achievement? What if seasonal demand drove most of the growth?

Before you judge, consider the pressure behind the performance.

Candidate honesty is not always a simple choice between truth and lies. Sometimes, people exaggerate. Sometimes, they remember events in ways that protect their confidence.

Your job is to understand what actually happened.

Why Candidates Present a Better Version of Themselves

A job interview is a performance with real consequences. Candidates want approval, an offer, and a better future.

Sociologist Erving Goffman described how people manage the impressions they create. In interviews, that often means highlighting strengths and hiding weaknesses.

Research by psychologist Robert Feldman also explored everyday dishonesty. In one study, about 60% of participants lied at least once during a ten minute conversation.

That finding does not tell us how many candidates lie. However, it challenges the idea that dishonesty happens only in exceptional circumstances.

Not every inaccurate story involves deliberate deception, either.

People often credit themselves for success and blame circumstances for failure. This tendency is called self serving bias.

A candidate may genuinely remember being the person who saved a project. Other team members may remember the same story differently.

The pressure to sell yourself can also encourage exaggeration. “Fake it till you make it” captures that pressure neatly.

Still, confidence and accuracy are not the same thing.

Why Body Language Cannot Prove Candidate Honesty

It is tempting to believe that experience makes you a reliable lie detector.

You might watch for nervous laughter, folded arms, or wandering eyes.

Yet a review by Charles Bond and Bella DePaulo found something less reassuring. People identified truth and lies with average accuracy of about 54%.

That is only slightly better than chance.

An honest candidate may feel nervous. A dishonest candidate may appear relaxed.

Therefore, do not treat discomfort as proof of deception. Focus instead on claims you can explore and verify.

1. Ask for Details, Not Impressions

Broad claims sound impressive. Specific questions make those claims easier to evaluate.

When someone describes a major achievement, ask:

• What was the starting point?

• Who else worked on the project?

• What did you personally decide or deliver?

• What went wrong?

• How did you measure the result?

For example, “I increased revenue by 40%” needs context.

Was that growth measured against the previous month or year? Did prices change? Did the team gain more resources?

Details help you understand the achievement. However, detail alone does not prove that a story is true.

2. Clarify What “We” Actually Means

Team achievements matter. Using “we” is not automatically a warning sign.

However, you still need to understand the candidate’s contribution.

Ask a simple follow up question:

“What were you personally responsible for?”

Then explore the answer.

What could they decide independently? What did another person own? Which result depended directly on their work?

This approach separates teamwork from an unclear account of personal responsibility.

3. Ask Questions Beyond the Rehearsed Story

Candidates often prepare polished examples before an interview. Preparation itself is not suspicious.

Still, additional questions can reveal how well someone understands their own example.

Try asking:

• What happened immediately before that decision?

• Which alternative did you reject?

• What would your manager describe differently?

• What would you change today?

Research associated with psychologist Aldert Vrij has explored unexpected questions in deception detection.

However, an interview is not a laboratory test. Do not treat a pause or an imperfect answer as proof of lying.

Use these questions to explore experience, not to create a trap.

4. Build Rapport Without Playing Detective

Start with a friendly conversation. Explain the interview format and give the candidate time to settle.

However, avoid treating casual conversation as a reliable honesty baseline.

Someone may speak comfortably about their journey to the office. Discussing a failed project can feel very different.

A change in tone may reflect stress, uncertainty, or careful thought.

If an answer becomes unclear, ask for clarification. Do not guess what the candidate’s body language means.

5. Separate Exaggeration From Fabrication

Taking too much credit and inventing a qualification are different problems.

Both deserve attention. However, they should not automatically receive the same response.

Clarify an inflated achievement. Verify important factual claims through appropriate checks.

Depending on the role, those checks may include:

• Relevant qualifications

• Employment dates

• Previous responsibilities

• Professional references

Give candidates an opportunity to explain discrepancies before drawing conclusions.

Make Candidate Honesty Easier to Assess

The goal is not to catch someone lying. It is to understand the person behind the presentation.

Ask consistent questions. Explore individual contributions. Check important claims.

Also, leave room for imperfect answers.

“I made a mistake, and here is what I learned” can start a useful discussion. It is not automatic proof of trustworthiness.

Treat the interview as a professional conversation, not an interrogation.

A polished story may impress you. A clear, specific, verifiable account gives you more to work with.
