How to Interview Someone for a Job Role (Step-by-Step Guide for Hiring Managers)

Interviewing someone for a job role is one of the most important decisions a manager makes, because the people you hire directly influence your team’s performance, morale, and long-term results. Every new employee brings their skills, habits, and attitudes into your organization. A strong hire can lift productivity, improve collaboration, and even inspire others. A poor hire, however, can drain time, create conflict, damage customer relationships, and lead to repeated recruitment costs when you eventually have to replace them. In other words, the quality of your interviews quietly shapes the future of your business.

A great interview isn’t just a casual conversation; it’s a structured opportunity to understand how a candidate thinks, behaves, and performs in real situations. Done well, it helps you identify the right person for the role, protect your company from bad hires, and strengthen your team culture by bringing in people who share your values and work ethic. A weak or unplanned interview, on the other hand, often turns into guesswork. It opens the door to personal bias, favors confident talkers over genuinely capable people, and almost always increases the risk of costly hiring mistakes.

Modern hiring research is very clear: structured interviews—with predefined questions, clear evaluation criteria, and a consistent process—are more predictive and fairer than unstructured, “chatty” interviews that rely on instinct. When you use the same core questions and scoring system for all candidates, you compare people based on evidence, not on who you happen to “click” with. This consistency improves decision-making, reduces bias, and creates a more positive and transparent experience for candidates.

This guide will walk you step-by-step through how to interview someone for a job role, from understanding the position and designing your questions to running the interview, scoring responses, staying legally compliant, and making a final decision you can confidently stand behind. Whether you’re a new manager or an experienced recruiter looking to refine your approach, you’ll find practical, repeatable methods you can start using in your next interview.

1. Start With the Job, Not the Candidate

Before you schedule a single interview, get crystal clear on what success in the role looks like.

1.1 Do a simple job analysis

List out:

• Core responsibilities – What will this person actually do day to day?

• Must-have skills – Technical skills, tools, qualifications, languages.

• Key soft skills – Communication, problem-solving, teamwork, leadership, adaptability.

• Values and culture fit – Behaviours that succeed (and fail) in your organization.

This job analysis forms the foundation of your interview guide and scorecard. Structured interviews typically start from clearly defined competencies. 

1.2 Turn requirements into competencies

Group your list into 5–8 competencies, for example:

• Technical expertise

• Problem-solving and decision-making

• Collaboration and communication

• Customer focus

• Ownership and reliability

• Leadership or potential to lead (if relevant)

• Alignment with company values

Each competency will later get interview questions and a rating scale.

2. Choose the Right Interview Format

There isn’t only one “correct” way to interview, but some formats are clearly more effective than others.

2.1 Structured vs. unstructured interviews

• Structured interview

  • Every candidate gets the same core questions, asked in the same order.

  • Answers are scored using a predefined rating scale.

  • Proven to improve fairness, reduce bias, and increase predictive validity. 

• Unstructured (conversational) interview

  • Questions are improvised.

  • Conversations often drift, and different candidates get very different questions.

  • Comfortable but inconsistent and more prone to bias. 

For most organizations, the best option is structured or semi-structured: a consistent core of questions, plus a little flexibility for follow-up.

2.2 Panel, one-to-one, or multiple rounds?

• One-to-one interviews – Good for building rapport; best for early screening.

• Panel interviews – Two or more interviewers; stronger for reducing individual bias and getting multiple perspectives.

• Multiple stages – Phone/online screen → skills/technical round → culture/values panel → final decision.

Choose a format that matches the seniority of the role, the complexity of responsibilities, and your internal capacity.

3. Build a Structured Interview Guide

Your guide is a document that outlines:

• Introduction and flow

• Questions for each competency

• Follow-up prompts

• Closing questions and next steps

3.1 Use behavioural and situational questions

The most effective interviews rely heavily on behavioural and situational questions:

• Behavioural questions ask about what the candidate has done in the past.

  “Tell me about a time you had to handle a difficult client.”

  Past behaviour is one of the best predictors of future performance.

• Situational questions present a hypothetical scenario:

  “If you were given three urgent tasks with similar deadlines, how would you prioritize them?”

Both types help you see how the candidate thinks and acts, not just what they claim to know.

3.2 Use the STAR method as your backbone

Train candidates (and interviewers) around STAR responses:

• Situation – Context

• Task – What needed to be done

• Action – What they did

• Result – Outcome, with numbers where possible

This structure keeps answers concrete and makes them easier to evaluate.

3.3 Example questions by competency

Problem-solving & decision-making

• “Describe a complex problem you solved. What options did you consider and why did you choose your final approach?”

• “Tell me about a time when you made a decision with incomplete information.”

Teamwork & communication

• “Give an example of a time you had to work with a difficult teammate. What happened and how did you handle it?”

• “Describe a situation where you had to explain a complex idea to a non-expert.”

Customer focus

• “Tell me about a time you turned around an unhappy customer or stakeholder.”

• “Describe your approach to balancing customer requests with company policies.”

Ownership & reliability

• “Share a time you made a mistake at work. What did you do afterwards?”

• “Give an example of a project where you had to manage your own deadlines without close supervision.”

You can expand these with your own role-specific questions or adapt examples from professional bodies like SHRM. 

4. Create a Clear Interview Scoring System

Without a scoring system, it’s easy to rely on “I just liked them”, which is risky and biased.

4.1 Build a simple rating scale

For each competency, create a 1–5 scale:

1. Poor – Doesn’t meet the requirement; can’t give relevant examples.

2. Below expectations – Limited evidence; vague answers.

3. Meets expectations – Solid examples; covers basics well.

4. Above expectations – Strong, detailed examples; exceeds the standard.

5. Outstanding – Exceptional performance; multiple strong examples, clear impact.

Use the same scale for each candidate. Tools like scoring sheets and behavioural interview matrices help standardize decisions and reduce bias.

4.2 Use a scorecard or matrix

Your interview scorecard should include:

• Candidate name and role

• Competencies

• Questions asked

• Rating (1–5) for each competency

• Space for brief notes and specific evidence

At the end, you sum or average the scores and combine them with reference checks and work samples to decide.

5. Prepare Before the Interview

A professional, respectful process leaves a strong impression on candidates—even those you don’t hire.

5.1 Share the basics with the candidate

In your invitation email:

• Confirm date, time, and time zone.

• Share location or video link, expected duration, and names/roles of interviewers.

• Let them know what to expect:

  “You’ll have a 45-minute interview covering your experience, problem-solving skills, and culture fit. We’ll also leave time for your questions.”

5.2 Prepare your side

• Review the candidate’s CV, cover letter, LinkedIn, portfolio.

• Highlight areas you want to explore further.

• Print or open your interview guide and scorecard.

• Make sure your meeting room or video setup is ready and distraction-free.

Professional HR bodies stress that interviewer preparation significantly improves candidate experience and interview quality. 

6. How to Conduct the Interview (Step-by-Step)

Here’s a simple flow you can follow for a 45–60 minute interview.

6.1 Opening (5 minutes)

• Greet the candidate warmly and offer water or check their audio/video.

• Build quick rapport:

  ADVERTISEMENT

  “Thanks for taking the time today. How has your day been so far?”

• Explain the structure:

  “We’ll spend about 40 minutes going through your experience and some scenario questions, then leave time for your questions at the end.”

This reduces anxiety and helps the candidate perform at their best.

6.2 Confirm basics (2–3 minutes)

• Briefly confirm their understanding of the role.

  “In your own words, what attracted you to this position?”

• Correct any misunderstandings and give a concise description of the role and team.

  
  

6.3 Core questions (25–35 minutes)

For each competency:

1. Ask your behavioural or situational question.

2. Use probing questions if needed:

   • “What was your exact role?”

   • “What options did you consider?”

   • “What happened as a result?”

3. Take notes in bullet points, focusing on facts and outcomes, not personal impressions.

4. Rate each answer using your scale while it’s still fresh.

Maintain neutral body language, listen actively, and avoid interrupting unnecessarily.

6.4 Cultural and values alignment (5–10 minutes)

Ask questions such as:

• “Tell me about the type of work environment where you do your best work.”

• “Describe a time you disagreed with a decision at work. What did you do?”

• “What does ‘ownership’ mean to you in a team setting?”

You’re trying to see whether their working style fits your company values.

6.5 Candidate questions (5–10 minutes)

Always leave time for their questions. Good candidates will ask about:

• Team structure and expectations

• Success metrics in the first 90 days

• Opportunities for growth

• Tools, processes, or leadership style

How they ask questions often reveals their priorities and level of preparation.

6.6 Closing (2–5 minutes)

• Thank them for their time.

• Explain the next steps and timeline:

  “We’re finishing interviews this week and expect to update you by Friday.”

• Confirm the best way to contact them.

A respectful closing reinforces your employer brand even if they’re not selected.

7. Legal and Ethical Interviewing: Questions You Must Avoid

It’s not just about being polite; it’s also about compliance. Employment laws in many countries restrict questions related to protected characteristics like race, religion, sex, age, disability, and more. 

7.1 Avoid questions about protected characteristics

Do not ask about:

• Age or date of birth

• Marital status, children, pregnancy plans

• Race, ethnicity, or nationality (beyond legal right to work)

• Religion or religious practices

• Sexual orientation or gender identity

• Disabilities or medical conditions (beyond ability to perform essential job functions with or without accommodation)

Instead, focus on whether the candidate can perform the job’s essential functions and meet any legal requirements (e.g., shift patterns, travel, lifting requirements).

7.2 Reduce bias in your process

• Use structured questions and scoring instead of gut feeling. 

• Have more than one interviewer where possible.

• Train interviewers to recognize confirmation bias (liking people who are similar to them) and stereotypes.

• Document your reasons for decisions based on job-related criteria, not personal preferences.

This protects you legally and leads to better, fairer hiring decisions.

8. After the Interview: Evaluate and Decide

The interview isn’t over when the candidate leaves the room; your evaluation process is just as important.

8.1 Complete your notes immediately

• Finalize your ratings for each competency.

• Add a short overall summary, focusing on:

  • Strengths

  • Risks or gaps

  • Specific evidence from their answers

Avoid vague comments like “great vibe” or “not a culture fit” without details.

8.2 Debrief with other interviewers

If there were multiple interviewers:

• Hold a brief debrief meeting.

• Compare scores and evidence.

• Discuss where you differed and why.

• Make sure the final decision is based on consistent criteria, not the loudest voice.

  
  

8.3 Combine with other data

Your interview is one part of a broader selection process, which may include:

• Work samples or test tasks

• Reference checks

• Skills assessments

Where possible, weigh real performance evidence higher than interview charisma.

9. Tips for Remote or Video Interviews

Many interviews now happen on Zoom, Teams, or similar platforms. The fundamentals are the same, but there are a few extra details to manage. 

• Test your camera, microphone, and internet before the call.

• Choose a quiet, well-lit, neutral background.

• Make eye contact by looking into the camera regularly.

• Allow a little extra time for connection delays.

• Share any online assessments or documents in advance.

Be especially patient with technical hiccups; a dropped call doesn’t reflect the candidate’s ability to do the role.

10. Common Interviewing Mistakes to Avoid

1. Winging it with no plan

   • Leads to inconsistent questions and unfair comparisons.

2. Talking more than you listen

   • Aim for the candidate to speak around 70% of the time.

3. Asking leading questions

   • “You’re comfortable with overtime, right?” instead of “How do you feel about working occasional overtime?”

4. Judging on first impressions

   • Give candidates time to warm up before forming strong opinions.

5. Ignoring red flags because you like them

   • Charisma doesn’t replace evidence of skills and reliability.

6. Failing to follow up with candidates

   • Damages your employer brand and can hurt future hiring.

12. FAQ: Practical Questions About Interviewing Candidates

12.1 How long should a job interview last?

For most roles, 30–60 minutes is ideal:

• 30–40 minutes for junior roles or first-round screens

• 45–60 minutes for more senior or final-round interviews

Longer sessions work better as two shorter interviews than a single marathon.

12.2 How do you start an interview professionally?

• Greet the candidate by name.

  ADVERTISEMENT

• Thank them for their time.

• Explain the structure and duration.

• Ask a simple, low-pressure question (e.g., “How was your journey?” or “How has your day been?”) to help them relax.

  
  

12.3 What are good first questions to ask?

• “Can you give me a quick overview of your background and how it led you to this role?”

• “What made you interested in this position and our company?”

These help you understand their motivation and communication style.

12.4 Should you share interview questions in advance?

For highly technical roles, sharing broad themes (not exact questions) is often helpful:

“We’ll focus on your experience leading projects, your technical skills in X, and how you solve problems with stakeholders.”

This leads to higher-quality, more thoughtful answers.

12.5 How do you know if an interview went well?

Look for:

• Clear, structured answers with concrete examples.

• Evidence that they’ve solved similar problems before.

• Questions that show curiosity about the role and company.

• Alignment between their expectations and what you can offer.
