The most effective way to interview someone for a job is to use a structured, behavior-based interview format. This means asking every candidate the same set of questions focused on how they have handled specific situations in the past. A structured interview is far more predictive of future job performance than an unstructured conversation. It reduces bias and makes it easier to compare candidates fairly.
Start by defining the key competencies for the role. For example, if the role requires problem-solving, your question might be: “Tell me about a time you had to solve a complex problem with limited resources.” Then, use the STAR method (Situation, Task, Action, Result) to dig deeper. Ask for specific details about the context, the task they faced, the actions they took, and the outcome. This approach moves beyond hypothetical answers and into real evidence.
To ensure you are covering all bases, create a structured interview guide with a consistent scoring rubric. Score each candidate on a 1-to-5 scale for each competency immediately after their response. This prevents the “halo effect,” where one strong answer influences your entire impression.
| Interview Method | Predictive Validity | Key Feature |
|---|---|---|
| Unstructured Interview | Low (about 20%) | Casual conversation, no standard questions |
| Structured Behavioral Interview | High (about 60-70%) | Standardized questions, scoring rubric |
Beyond the questions, pay attention to the logistics. Plan for a 45-minute interview with 5-7 questions. Leave 5-10 minutes for the candidate to ask questions, which reveals their engagement and preparation. Take notes immediately, but ask for permission first. Finally, avoid leading questions like “You’re good at leading teams, right?” and stick to neutral, open-ended phrasing. The goal is to collect objective data, not to confirm a gut feeling. Your interview process should be a reliable assessment tool, not a friendly chat.

Honestly, I focus on listening more than talking. I’ll ask a simple question like “What’s the biggest challenge you faced in your last role?” and then just stay quiet. I want to see how they structure their thoughts without me guiding them. If they ramble, that’s a red flag. If they are concise and direct, that’s a good sign. I also pay close attention to the questions they ask me at the end. A candidate who asks about team culture or project failures is usually more thoughtful than one who only asks about salary and vacation days.

My approach is all about stress-testing for soft skills. I’ll throw in a curveball like “Give me three reasons why I should not hire you.” The way they handle pressure reveals a lot about their emotional intelligence. I also watch for non-verbal cues, like eye contact and posture. Someone who can keep their composure and give a thoughtful, honest answer usually handles workplace conflict well. A perfect, rehearsed answer is often less valuable than a genuine, slightly messy one.

I believe in the “two-interviewer” rule. I always have a colleague from a different department sit in. They see things I miss, like whether the candidate is good at explaining complex ideas to a non-expert. We use a shared scoring sheet and debrief immediately after. I also avoid asking about hobbies or personal life to keep it professional. The focus is strictly on the job. If we can’t agree on a candidate within 15 minutes of discussion, that’s usually a sign to move on to the next person.

I look for curiosity and adaptability. I’ll ask about a project that failed and what they learned from it. The best candidates don’t blame others; they talk about process improvements. I also use a practical task during the interview, like a 10-minute case study. Watching someone think on their feet is more valuable than hearing a rehearsed story. I’ll even ask, “What would you change about our current workflow?” A strong candidate will have done their homework and offer specific, respectful suggestions. That shows real initiative and genuine interest.
