Effective Interviewing At a Glance

A strong interview is structured around the role, not the interviewer’s instincts. That means defining what success looks like, asking consistent questions tied to the role requirements, and evaluating candidates against clear criteria. When interviews focus on evidence instead of chemistry, hiring decisions become fairer, more consistent, and predictive of performance.

Why Interviews Matter

Interviews play a major role in hiring decisions. By the time a candidate reaches this stage, their resume has been reviewed, and their qualifications are generally clear. The interview is when hiring teams decide whether a candidate can truly succeed in the role.

That responsibility isn’t easy. In a survey of more than 2,700 managers, 50% said interviewing candidates is the hardest part of the hiring process.

Part of the challenge is that interviews rely heavily on human judgment. Without clear criteria, interviewers may focus on confidence, communication style, or how well a candidate “clicks” with the team. 

When interviews go wrong, the impact is real: mis-hires, slower hiring decisions, higher turnover, and inconsistent candidate experiences. Conducted well, however, interviews can provide the evidence hiring teams need to make confident, well-informed decisions.

Preparing to Conduct an Interview

A strong interview starts well before you meet the candidate. Preparation ensures the conversation focuses on the requirements of the role rather than first impressions or personal preferences.

Use the following steps to prepare:

1. Clarify what success looks like in the role
Identify the outcomes the new hire should achieve in the first 6–12 months. These performance goals help interviewers focus on what the role truly requires.

2. Identify required skills and expertise
Outline the technical knowledge, tools, and capabilities needed to perform the job effectively.

3. Define the competencies tied to performance
Determine which competencies, such as communication, problem-solving, or decision-making, are most important for success in the position.

4. Consider the behavioral demands of the role
Think about the work style and behavioral strengths that will help someone succeed within the team and work environment. This is often described as culture fit, but it should focus on how someone works and collaborates, not simply personality similarities.

5. Align the hiring team before interviews begin
Recruiters and hiring managers should agree on role expectations and what strong candidate responses will look like. This alignment keeps interviews consistent and focused.

6. Prepare consistent, role-related questions
Develop a set of questions in advance that connect directly to the job’s responsibilities. Asking well-designed strategic questions helps interviewers understand how candidates approach real work situations.

Interview Structure and Format

Interviews typically fall into two categories: structured and unstructured. The difference lies in how consistently questions are asked and how candidates are evaluated.

A structured interview follows a defined set of job-related questions and evaluates responses using consistent criteria. An unstructured interview is more conversational, with questions that change depending on the discussion. While this approach can feel more natural, it often makes it harder to compare candidates fairly.

Organizations also use different interview formats depending on the stage of hiring or the type of role. Common formats include:

• Phone interviews for early-stage screening
• Video interviews for remote or distributed hiring
• Panel interviews with multiple interviewers
• Behavioral interviews focused on past experiences
• Situational interviews based on hypothetical scenarios
• Technical interviews that assess role-specific skills

The format itself matters less than having a consistent, role-aligned approach. The most effective interviews ask job-related questions and evaluate candidates against the same expectations and criteria.

How to Conduct an Interview in 7 Steps

A well-run interview follows a clear process. These steps help interviewers gather consistent, job-relevant information so candidates can be evaluated fairly and confidently.

1. Review the Role and the Candidate in Advance

Start by reviewing the role requirements, so your questions reflect the skills and behavioral strengths needed for success. Look through the candidate’s resume as well and note anything worth exploring further, such as a career change, a gap in employment, or a major result they highlight. The goal is simply to prepare thoughtful questions, not to form an opinion about the candidate before the interview begins.

2. Open the Interview and Set Clear Expectations

Open the interview with a brief greeting and introduce everyone involved in the conversation. Let the candidate know how the interview will work, how long it should take, and the types of topics you plan to cover. Clarifying the process early helps candidates feel more comfortable and understand what to expect after the discussion.

3. Ask Structured, Behavioral Questions

This is the most important part of the interview. The goal is to understand how the candidate has handled real work situations, since past behavior often provides the strongest clues about future performance.

Focus on questions that prompt candidates to describe specific experiences rather than general strengths. For example:

• “Tell me about a time when you had to solve a difficult problem under pressure.”
• “Describe a situation where you had to influence someone who initially disagreed with you.”
• “Tell me about a time you had to prioritize competing deadlines.”
  

Questions like these reveal the situation the candidate faced, the actions they took, and the results they achieved, making it easier to evaluate real evidence instead of relying on impressions.

Each question should connect to an important skill or competency required for the role. For example, leadership roles may focus on decision-making and influence, while analytical roles may emphasize problem-solving or critical thinking.

Consistency also matters. Asking every candidate the same core questions makes it easier to compare responses and evaluate candidates fairly. Follow-up questions can vary, but the main questions should remain consistent.

Using a mix of question types can also provide deeper insight. Behavioral questions focus on past experiences, such as:

• “Tell me about a time you had to resolve a conflict with a coworker.”
• “Describe a situation where you had to meet a tight deadline.”

Situational questions, on the other hand, present hypothetical scenarios:

• “What would you do if two important projects had the same deadline?”
• “How would you handle a disagreement with a manager about priorities?”

Both approaches help interviewers understand how candidates approach challenges and make decisions at work.

4. Ask Follow-Up Questions to Clarify Details

Strong interviews don’t stop at the first answer. Follow-up questions help you understand what actually happened in the situation.

Ask questions such as:

• “What exactly did you do?”
• “What was the outcome?”
• “What challenges did you face?”

The goal is to move past general statements and focus on the candidate’s specific actions and results. This helps you understand their real contribution and evaluate their experience more accurately.

5. Take Clear, Job-Related Notes

Document key details from the conversation. Good notes capture specific examples, actions, and outcomes tied to the skills required for the role.

Avoid vague comments such as “seems confident” or “good vibe.” Notes should focus on observable information that can be evaluated later.

6. Manage Time and Invite Candidate Questions

Keep track of time so you can cover the key topics you planned to discuss while still leaving space at the end for the candidate’s questions. Remember, interviews are a two-way process; candidates are also evaluating whether the role and organization are right for them.

7. Document Your Evaluation Right Away

After the interview, record your evaluation while the conversation is still fresh. Summarize how the candidate demonstrated the skills and competencies required for the role, using specific examples from the discussion.

Consistent documentation helps the hiring team compare candidates fairly. Many applicant tracking systems include evaluation forms or scorecards, but the most important thing is capturing clear, role-focused feedback across the hiring team.

After the Interview

Once the interview ends, the evaluation process begins. Taking a structured approach helps ensure hiring decisions stay focused on the role rather than personal impressions.

Begin with a brief debrief meeting. Each interviewer should share their evaluation first before discussing the candidate as a group. This helps prevent early opinions from influencing others.

Interview feedback should also be considered alongside other hiring data, such as assessments, work samples, or technical exercises that provide additional evidence of a candidate’s ability to perform the role.

Once the team reaches a decision, communicate promptly with candidates about the outcome or next steps. Timely communication matters—34% of candidates assume they’ve been ghosted if they haven’t heard back within a week. Even a brief update helps set expectations and maintains a positive candidate experience.

How The Predictive Index Simplifies the Interview Process

Structured interviews work best when the role is clearly defined. That’s where The Predictive Index helps simplify the process.

The Predictive Index Job Assessment captures input from key stakeholders and translates it into an easy-to-read Job Target. This helps hiring teams align on the behavioral drives and cognitive demands required for success in the role before interviews begin.

From there, the PI Interview Guide helps interviewers focus on the areas that matter most. It generates questions based on the behavioral needs of the role and the candidate’s potential fit. For example, if a role requires strong attention to detail but a candidate is less likely to prefer structure or rules, the guide may suggest asking how the candidate manages detail-heavy work or stays organized. This helps interviewers explore potential gaps thoughtfully rather than relying on assumptions.

By introducing objective, job-related data before and during interviews, The Predictive Index helps hiring teams ask better questions and evaluate candidates more consistently.

Tools like PI Hire support this process by helping teams align upfront through collaborative job targeting, ensuring everyone involved in hiring is evaluating candidates against the same role requirements from the start.
