🚫 Biggest Interviewing Mistakes—and How to Avoid Them

Even seasoned interviewers fall into common traps that can lead to poor hiring decisions. Below are five mistakes that can undermine your interviews—plus quick tips on how to avoid them.

🕒 1. Failing to Dedicate Enough Time

Rushing through interviews or skipping the prep work is a recipe for hiring regret. Without a clear plan or structured question set, you risk missing signs of poor fit—or overlooking strong candidates.

Quick Tip: Block out prep time. Create or reuse structured question lists tied to job-specific competencies.

🔁 2. Being Inconsistent Across Candidates

Improvising interviews can lead to biased comparisons. Without a consistent format or scoring method, you can’t reliably compare answers across different applicants.

  • Use the same core questions for each candidate.
  • Apply a clear evaluation rubric (e.g., STAR method + 1–5 rating scale).

🗣️ 3. Talking Too Much

If you're talking more than 15–20% of the time, you're likely guiding the candidate’s responses. Skilled candidates may simply reflect your expectations rather than sharing authentic answers.

Quick Tip: Stick to open-ended questions. Listen actively, and probe with “Can you tell me more about that?”

😎 4. Getting Swayed by Surface Impressions

Don’t let charisma, confidence, or a sharp outfit cloud your judgment. The “halo effect” can make you ignore weak answers just because you like one aspect of the candidate.

Example: “I loved his tie” is not a valid hiring criterion.

🧠 5. Over-Interpreting Candidate Behavior

If you're not trained in behavioral psychology, avoid reading too much into micro-expressions or body language. Misinterpretation can unfairly bias your decision.

If something feels off, note it—but follow up with clarifying questions. And if deeper evaluation is needed, consult a professional.
