How to Overcome Bias in Recruitment

The hiring manager didn't mean to do it. Nobody ever does. But when the shortlist came back for the senior engineer role, all five candidates had gone to the same three universities. All five had worked at recognizable companies. All five fit a pattern that felt safe, familiar, and low-risk.

The candidate with the unconventional background, the one who taught themselves to code and had been contributing to open-source projects for years, never made it past the resume screen. Not because they weren't qualified. But because their path didn't match the shape of what "qualified" was expected to look like.

This is how bias works in hiring. Not through overt discrimination, but through a thousand small decisions that feel neutral in the moment. A resume that gets three minutes of attention instead of thirty seconds because the school name is recognizable. A candidate who gets the benefit of the doubt in an interview because they remind the interviewer of someone who succeeded before. A question that goes unasked because the candidate's background feels credible enough that probing further seems unnecessary.

Bias doesn't announce itself. It embeds in structure. And in tech recruitment, where the volume is high and the pressure to move fast is constant, it quietly shapes who gets seen and who gets overlooked.

The shortcuts we rely on

Recruiters and hiring managers don't have unlimited time. When reviewing hundreds of applications, the brain looks for shortcuts. Patterns. Proxies for quality that let you make decisions quickly.

A degree from MIT or Stanford becomes a signal. So does experience at Google, Meta, or a well-funded startup. These aren't bad signals. People from these places are often strong. But they're not the only strong candidates, and relying too heavily on them means you're filtering by pedigree, not by capability.

The problem compounds in interviews. Research shows that interviewers form an impression in the first few minutes of a conversation, and the rest of the interview is often spent confirming that impression rather than testing it. A candidate who speaks confidently and uses the right jargon gets coded as competent. A candidate who's more thoughtful, who pauses before answering, who doesn't perform as smoothly in conversation, gets coded as uncertain.

None of this is intentional. But it's systemic. And it results in hiring processes that reward people who look and sound like the people who've been hired before, while undervaluing people who don't fit the pattern but have the skills to do the job.

What gets filtered out

Bias doesn't just affect individual candidates. It affects entire categories of talent.

Career changers get filtered out because they don't have "enough years" in the field, even if they've built a portfolio that demonstrates real skill. People who took time off for caregiving or health reasons get filtered out because there's a gap on the resume. International candidates get filtered out because their experience doesn't map neatly to U.S. company names or because their English has an accent, even if their technical ability is exceptional.

Self-taught developers, bootcamp graduates, and people from non-traditional educational backgrounds face an uphill battle. Their resumes don't have the markers that make recruiters stop and look. So they get skimmed, not studied. And if they do make it to an interview, they're often held to a higher standard of proof than someone with a CS degree from a target school.

The irony is that many of these candidates are hungrier, more resourceful, and better problem-solvers than their more traditionally credentialed peers. They had to be. They didn't have a clear path handed to them. They built one.

But manual screening processes, especially under time pressure, don't surface that. They surface what's easy to verify and what feels safe.

The interview as amplifier

Bias doesn't stop at the resume screen. It shows up in how interviews are conducted and evaluated.

Different candidates get asked different questions. One person might be asked a softball behavioral question, while another gets a deeply technical one. The interviewer doesn't realize they're calibrating difficulty based on unconscious assumptions about the candidate's background. A candidate from a name-brand company might be asked to "walk through" their experience, while a candidate from a lesser-known company is asked to "prove" theirs.

Then there's the evaluation. After the interview, the hiring team debriefs. One person says the candidate was "sharp." Another says they were "a bit too quiet." A third says they "didn't seem like a culture fit." None of these assessments are tied to a rubric. None of them are based on consistent criteria. They're impressions, and impressions are where bias lives most comfortably.

The candidate who matched the interviewer's expectations gets described in positive, capability-focused terms. The one who didn't gets described in vague, affective terms. "Not sure they're ready." "Didn't feel right." "Something was off." These phrases don't describe skill. They describe discomfort with difference.

And because most companies don't record interviews or use structured evaluations, there's no way to go back and audit whether the process was fair. It's just memory, feeling, and whatever got written in the notes.

What fairness actually requires

Overcoming bias isn't about trying harder to be objective. Human beings aren't wired for perfect objectivity, especially under cognitive load. Fairness requires structure. It requires systems that don't rely on each individual making unbiased decisions, because that's not realistic at scale.

The first step is consistency. Every candidate for a role should be asked the same core questions. Not identical scripts, but the same areas of evaluation. If you're assessing problem-solving, every candidate should get a problem-solving question. If you're assessing communication, everyone should be asked to explain something complex. This sounds obvious, but it rarely happens in practice.

The second step is rubrics. Evaluations need to be tied to specific, observable criteria. Not "did they seem smart," but "were they able to break down a system design question into components and reason through tradeoffs." Not "did I like them," but "did they demonstrate understanding of the frameworks the role requires."

The third step is removing information that shouldn't influence the decision. In the early stages of screening, you don't need to know what someone looks like, where they're from, or what their name suggests about their background. You need to know whether they can do the job.

This is where tools like Expert Hire create a structural advantage. When every candidate goes through the same AI-led interview, whether it's Expert Vision for resume rounds, Expert Screen for technical evaluation the process is standardized by design. The AI doesn't see a resume halo. It doesn't get influenced by a candidate's accent or communication style. It asks the same questions, listens to the answers, and evaluates them against a rubric tied to skills, not proxies.

Candidates complete interviews on their own time, recorded and scored consistently. The recruiter and hiring manager review transcripts, video recordings, and structured scorecards. They see what the candidate actually said and how they approached the problems, not a distorted summary filtered through one person's memory and biases.

This doesn't mean the AI makes the hiring decision. It means the AI removes the inconsistency that lets bias seep in. Humans still decide who moves forward. But they're deciding based on comparable, structured information, not on gut feelings formed in the first three minutes of a call.

The business case for fairness

There's a moral case for reducing bias in hiring, and it's straightforward. People deserve to be evaluated on their ability, not on proxies that have nothing to do with the job.

But there's also a business case, and it's just as strong. Bias narrows your talent pool. It filters out people who could have been great. It makes your team less diverse, which makes it less effective. Homogeneous teams miss things. They have blind spots. They default to solutions that work for people like them, and they struggle to build products for people who aren't.

Reducing bias doesn't just make hiring fairer. It makes it better. You see more candidates. You evaluate them more accurately. You make decisions based on capability, not credentials. And you end up with stronger teams.

The companies that figure this out early will have an advantage. Not because they're more virtuous, but because they're tapping into a wider pool of talent and making better decisions about who to bring in.

Moving from intent to infrastructure

Most companies say they want to reduce bias in hiring. They run unconscious bias training. They talk about diversity and inclusion. They set goals. And then they go back to the same manual processes that let bias thrive, because no one has actually changed the structure.

Intent isn't enough. You can't train your way out of a system that's built to rely on shortcuts and gut feelings. You have to change the system.

That means standardizing interviews. It means using rubrics. It means recording and reviewing evaluations to see where patterns emerge. It means removing information that shouldn't matter and surfacing information that should. It means treating the early stages of hiring with the same rigor you apply to the final rounds.

And increasingly, it means using tools that build fairness into the process by design. Not as a nice-to-have feature, but as a structural necessity.

Bias isn't something you fix by trying harder. It's something you fix by building a process that doesn't depend on individual perfection. Because no one is perfect. But the system can be fair.
