AI Interviews May Be
Less Biased.
Why Don’t Candidates Believe It?

Candidates want an unbiased interview. They just do not believe AI can provide one.

1

Hardly anyone chose AI

<

I recently asked people whether they believed an AI interview would be less biased than a human interview.

Candidates want an unbiased interview. They just do not believe AI can provide one.

That response is interesting because most people have experienced bias during recruitment. They know interviewers form quick impressions. They know two interviewers can assess the same candidate differently. Yet they still trust a human interviewer more than a machine.

The interview begins before you speak

<

Human bias enters the process before the candidate answers the first question.

Comic panel: everything a recruiter is asked to hold in mind

The interviewer has already seen the candidate’s name, age, college, previous employers, location, career gaps and CV format.

Comic panel: a CV that creates a good impression

A candidate from a famous company may be assumed to be more capable before providing any evidence.

Someone who studied and grew up in South Mumbai may create one impression. Someone from a small town may create another.

Interviewers also assess candidates through their own life experiences.

Someone who built a career by staying with one company may see frequent job changes as a lack of loyalty. Someone who progressed by changing companies may see the same career as ambitious.

People value strengths similar to their own. They are also more likely to notice weaknesses they have personally struggled with.

💡

Interviewers rarely assess candidates from a neutral position. They assess candidates against themselves.

Then comes the pressure to break the ice.

Interviewers are told to begin with small talk and make the candidate comfortable. Sometimes that works. Sometimes the conversation becomes awkward. The candidate gives a short answer, does not smile enough or fails to respond enthusiastically to an irrelevant joke.

The interviewer switches off within two minutes.

The remaining interview may last another 30 minutes, but the decision has largely been made. The questions then become a search for evidence supporting that first impression.

A candidate can lose an interview before the actual interview has started.

Humans are confident judges of people

<

Daniel Kahneman experienced this while working with the Israeli Army.

Interviewers observed candidates completing a group exercise and predicted who would become an effective officer. They formed clear impressions and felt highly confident about their predictions.

The predictions had little relationship with what happened later.

Kahneman redesigned the process. Instead of asking interviewers to form an overall impression, he asked them to assess candidates separately against defined traits. Each trait had specific questions and an independent score. Combining those scores produced better predictions than relying on intuition.

💡

The lesson was simple: human confidence in judging people can be much higher than human accuracy.

Comic panel: going with your gut

They remain certain. They are also regularly wrong.

You can see a more entertaining version of this in The Traitors. Participants spend days living together, observing one another and discussing who might be the traitor. They then confidently vote out another innocent person.

This happens repeatedly.

Structured interviews work, but humans struggle to follow them

<

The solution to weak interviewing is not new.

Comic panel: the rules of a structured interview on a whiteboard

Ask every candidate the same core questions. Use behavioural questions wherever appropriate. Define the assessment criteria in advance. Score each answer independently before forming an overall judgment.

Research now places well-designed structured interviews among the strongest available predictors of future job performance.

Most recruiters and managers already know this.

The problem is following it.

Designing good questions and scoring criteria requires serious preparation. Listening carefully, recording evidence and scoring every answer requires mental effort. Repeating the same process across ten candidates becomes tiring.

Human beings also get bored easily.

They want some variety and fun, even during an interview. They change the questions, follow interesting tangents, skip areas already discussed or spend ten minutes talking about a common interest.

The first candidate and the tenth candidate may receive completely different interviews.

Structured interviews work. Human beings simply struggle to remain structured.

This is where AI has an advantage

<

AI does not become bored after asking the same question ten times.

Comic panel: the same first question to every candidate

It can ask the same core questions, make relevant follow-up enquiries and evaluate answers using consistent criteria.

Comic panel: it does not get tired or go off topic

It does not need an entertaining conversation. It does not become tired, lose concentration or switch off after a weak icebreaker.

It also does not compare a candidate’s career with its own career.

💡

AI’s advantage is not that it understands people perfectly. It is that it can follow a well-designed process every time.

The field experiment

A recent field experiment by Brian Jabarian and Luca Henkel tested this with approximately 70,000 applicants for entry-level customer-service roles.

Applicants were randomly assigned to an AI voice interviewer or a human recruiter. Human recruiters still reviewed the interviews and made the hiring decisions.

70,000applicants
12%more job offers
78%selected the AI interviewer

Candidates interviewed by AI received 12% more job offers. More of them started work, and retention improved without any decline in productivity. The AI interviews were more structured, covered more relevant topics and collected better information for the human decision-makers.

When candidates were given a choice, 78% selected the AI interviewer.

One study cannot tell us what will happen across every profession and seniority level. But this was not a demonstration using fictional candidates. These were real applicants applying for real jobs.

Why candidates still do not trust AI

<

One person responding to my poll explained the concern clearly:

“I might feel like I am not getting the opportunity to showcase my potential fully. Perhaps for mid manager to senior manager roles one might wonder if objective criteria based on AI is the right way to capture someone’s potential.”

This concern will become stronger for senior roles.

AI already has a reputation for hallucinating and confidently producing incorrect answers. People naturally question whether that machine should assess their capabilities or career.

There is also no real small talk, rapport or personal connection. Candidates may finish the interview without feeling heard, understood or validated.

But this creates another difficult question:

What evidence do we have that human interviewers can assess someone’s potential more accurately?

Potential is not clearly defined. Human interviewers often assess it through confidence, communication style, familiarity and resemblance to successful people they already know. That can feel more personal without necessarily being more accurate.

AI can also contain bias. Poor questions and biased criteria will produce poor assessments. But AI interviews leave transcripts, scores and results that can be reviewed across hundreds of candidates. Patterns can be detected and criteria can be corrected.

Human bias is usually hidden behind statements such as “not the right fit” or “something did not feel right.”

HR needs to explain this better

<

Candidates may hate AI interviews before they start. HR should explain the fairness case better.

Comic panel: our AI interview helps us hire faster

"Our AI interview helps us hire faster." "That sounds good for you, not for me."

Comic panel: explaining why we use AI interviews

"We use it to make the first round more fair and consistent." "If you had said that first, I would have reacted very differently."

Why we use AI interviews
  • Comparable questions
  • Same criteria
  • Less mood and fatigue
  • More job-focused first round

Candidates may prefer the interview that feels more human. But feeling fair and being fair are not necessarily the same thing.

AI does not need to be unbiased. It only needs to be less biased than the human interviewer.
