What Is Behavioral Interviewing and Why Does It Work?
Hiring decisions based on resumes and gut feelings often miss the mark. A candidate can look great on paper but struggle in the actual role. Behavioral interviewing changes that by focusing on what candidates have actually done, not what they say they would do.
The idea is simple: past behavior predicts future performance. When you ask candidates to walk you through real situations from their work history, you get concrete evidence of how they think, act, and handle challenges. That's far more reliable than asking "How would you handle a difficult coworker?"
Research backs this up. Studies show behavioral interviews are significantly better at predicting job performance than traditional unstructured interviews. And when done consistently, they also reduce unconscious bias in the hiring process.
How Does the STAR Method Help You Evaluate Candidates?
The STAR method is the backbone of behavioral interviewing. It stands for Situation, Task, Action, and Result. When you ask a behavioral question, you're guiding the candidate to walk through each of these four elements.
- Situation: What was the context or challenge?
- Task: What was their specific responsibility?
- Action: What steps did they actually take?
- Result: What happened, and what did they learn?
This structure helps you cut through vague, rehearsed answers. If a candidate says "We improved team communication," the STAR method lets you push further: Who did what? What changed? What was the outcome? You get real information instead of polished talking points.
What Competencies Should You Be Assessing?
Before you write a single question, get clear on what you're actually looking for. Every role has a set of core competencies — the specific behaviors that predict success in that position. These might include:
- Problem-solving and critical thinking
- Adaptability under pressure
- Collaboration and communication
- Leadership and decision-making
- Conflict resolution
Don't try to assess everything in one interview. Pick three to five competencies that matter most for the role and build your questions around those. This keeps the interview focused and makes it easier to compare candidates fairly.
How Do You Write Behavioral Interview Questions That Actually Reveal Something?
Good behavioral questions are specific and rooted in real workplace situations. They typically start with "Tell me about a time when..." or "Describe a situation where..."
Here are a few examples that tend to surface useful information:
- Tell me about a time you had to manage multiple competing deadlines. How did you decide what to prioritize?
- Describe a situation where you disagreed with a decision your manager made. What did you do?
- Give me an example of a time you had to adapt quickly to an unexpected change at work.
- Tell me about a project that didn't go as planned. What happened, and what did you take away from it?
The best questions don't have one "right" answer. You're listening for how the person thinks and how they handle real pressure — not whether they hit the perfect talking points.
How Does Behavioral Interviewing Help Reduce Hiring Bias?
One of the biggest advantages of behavioral interviewing is consistency. When every candidate answers the same set of questions and gets scored against the same criteria, it's much harder for personal impressions to drive the decision.
Traditional interviews are full of moments where bias sneaks in — favoring someone because they went to the same school, seem more confident, or remind the interviewer of themselves. Behavioral interviewing doesn't eliminate bias entirely, but it gives you a structured way to make comparisons based on actual evidence.
Using a scoring rubric helps even more. Rate each response on a defined scale tied to the competency you're assessing. This forces evaluators to articulate why they're rating someone highly — not just go with a gut feeling.
What Are Common Mistakes to Avoid in Behavioral Interviews?
Even well-intentioned interviewers make mistakes that undermine the process. A few to watch for:
- Accepting vague answers: If a candidate says "we" instead of "I," ask follow-up questions. You need to know their specific contribution.
- Not taking notes: Memory fades fast. Write down key details during the interview so you can evaluate responses accurately later.
- Inconsistent questioning: If different candidates get different questions, you can't fairly compare them. Stick to your prepared list.
- Rushing through: Give candidates enough time to think and answer fully. Silence isn't a bad thing — it often means they're recalling a real example.
How Can You Make Behavioral Interviewing Part of a Broader Hiring Process?
Behavioral interviewing works best when it's part of a structured hiring system — not a standalone step. Pair it with skills assessments, work samples, or structured reference checks to build a fuller picture of each candidate.
Train your interviewers so everyone on the panel understands how to ask follow-up questions and score responses consistently. Debrief together after each interview while the conversation is still fresh. And review your outcomes over time — are the candidates you hire through behavioral interviews actually performing better and staying longer?
If yes, you're on the right track. If not, it's worth revisiting your questions and scoring criteria.
Conclusion
Behavioral interviewing isn't complicated, but it does require preparation. You need to know what you're looking for, ask questions that actually surface useful information, and evaluate responses consistently across all candidates.
Done well, it takes a lot of the guesswork out of hiring. You spend less time on polished first impressions and more time on concrete evidence of how someone actually works.
If you want to build a hiring process that consistently finds the right people, behavioral interviewing is one of the most reliable tools you have. And the right platform can make it even easier to implement at scale.
