Beware of Your Unconscious Bias in Interviewing

When it comes to job interviews, we’re all guilty of bias whether we know it or not. Unconscious bias in interviewing is an obstacle to hiring a diverse and multi-talented team. Luckily, most hiring managers want to minimize bias whenever possible, both to ensure that quality talent is fairly hired as well as to protect against legal repercussions that may result from the unrecognized bias involved.A photo of a red-haired young woman showing thumbs up and thumbs down which is typical when you have unconscious bias in interviewing

Awareness is the first step towards overcoming unconscious bias in interviewing. Here’s what you need to know. 

Why Does Bias in Interviewing Matter?

Unconscious bias in interviewing is tricky because, by its very design, we’re often unaware that it’s actually happening. When asked, most hiring managers would insist that they’d never discriminate against a candidate for qualities like race, sex, religion, social class, or sexuality. In fact, it’s illegal to discriminate against protected classes.

Yet when unconscious bias in interviewing comes into play, these factors can influence us whether we know it or not. Bias in interviewing doesn’t always look like blatant discrimination, but can often prevent us from hiring quality candidates nonetheless. 

Common Interview Biases

Unconscious bias in interviewing can take many different shapes depending on what bias is in effect. Here are a few of the most common types of interview bias to look out for:

  • Anchoring bias: In anchoring bias, the first piece of information you hear can influence the situation. For example, if you know right away that a candidate earns well below market value for their work, it will be difficult to consider them for a higher salary. 
  • Contrast bias: This type of bias occurs when you compare candidates to each other rather than comparing each one to the job description at hand. The standards become distorted as the interview process becomes about which candidate seems most impressive compared to the others, not which one would best suit the job. 
  • First impression bias: Similar to anchoring bias, putting too much pressure on a first impression can lead to unfair discrimination. If a candidate seems overly nervous or flustered, that will color the rest of your interactions with them even if they compose themselves later in the interview. 
  • Fundamental attribution bias: This type of unconscious bias in interviewing leads to interviewers assigning personality traits to a candidate’s external circumstances. For example, if a candidate is dressed shabbily, the interviewer might assume they are lazy or careless without considering that a financial emergency could be to blame. 
  • Gut feeling bias: As the name suggests, this type of bias in interviewing happens when you trust your gut feeling more than you trust the facts at hand. It’s important to listen to your intuition, but that shouldn’t be the basis of the hiring process. 
  • Halo/horn-effect bias: If an interview is going well, we tend to assume the best about the candidate as a person; the horn effect is the opposite of this, where if things are going poorly, we assume negative things about the candidate. 
  • Negative emphasis bias in interviewing: This bias happens when a small amount of negative information unfairly influences the decision-making process and causes the interviewer to think negatively about the candidate in general.  
  • Non-verbal bias: Body language, or non-verbal cues, are incredibly easy to misinterpret. Don’t let them influence your hiring decision more than the interview itself. 
  • Recency bias: One of the most common types of bias in interviewing is recency bias. Here, the last candidate you interview will make a disproportionately strong impression just because they were the most recent, and therefore most memorable, one in your mind. 
  • Similarity bias: The similarity bias makes us think that candidates who are similar to us are automatically better. Of course, it takes a diverse team of different perspectives to truly achieve success.
