Most employers train managers on what not to ask during an interview—but stopping there leaves a critical gap. To truly hire well, supervisors and hiring managers need to know how to prepare for a valid, reliable, and insightful interview.

This guide focuses on what to do before the interview to set yourself—and your candidates—up for success.


Why Interview Preparation Matters

The interview is one of the most important steps in your hiring process. It’s your chance to go beyond a resume and uncover the candidate’s potential, mindset, and alignment with your team and company. But great interviews don’t happen by accident—they start with thoughtful preparation.


  1. Know the Job Inside and Out

Before you speak to candidates, review:

The job description and any stretch goals for the role

Key responsibilities and what success looks like

Tools, equipment, or systems used

Working conditions, schedules, and performance expectations

You need to fully understand the role in order to evaluate candidates accurately and answer their questions honestly.


  1. Understand the Metrics for Success

What defines success in this role?

Are there clear production or efficiency targets?

What specific knowledge, skills, and abilities (KSAs) lead to top performance?

Look at current or former successful employees in similar roles. What qualifications, experiences, or traits helped them excel?


  1. Prepare the Right Interview Questions

Good questions are:

Job-related

Open-ended (avoid yes/no answers)

Designed to reveal real examples of experience, problem-solving, and adaptability

Formulate your questions based on the KSAs required. Tailor them to the specific demands of the role—but be consistent enough to compare candidates fairly.


  1. Review Candidate Materials in Advance

Don’t scan resumes for the first time in the interview. Come prepared by reviewing:

Resume or application form

Notes from phone screenings or pre-interview assessments

Any correspondence or reference information you already have

This saves time, shows professionalism, and allows you to ask deeper questions during the interview.


Final Thought: Your Preparation Sets the Tone

When you’re organized, informed, and intentional, the candidate experience improves—and so does your ability to make a strong hiring decision.
