How to Conduct an Interview: Practical Step-by-Step Guide for Interviewers

Knowing how to conduct an interview is essential for hiring managers, team leads, and anyone responsible for evaluating candidates. A well-run interview balances consistent assessment with a respectful candidate experience, reduces bias, and improves the likelihood of selecting the right person for the role.

How to Conduct an Interview: Step-by-Step Process

1. Prepare: define the role and criteria

Begin by reviewing the job description, updating the list of core responsibilities, and identifying 3–6 key competencies (technical skills, communication, problem solving, culture fit) required for success. Translate each competency into observable behaviors so questions and scoring focus on evidence, not impressions.

2. Choose an interview structure

Structured interviews—where each candidate receives the same core questions and answers are scored against a rubric—consistently predict job performance better than unstructured conversations. Decide whether to use a behavioral format (past examples), situational format (how a candidate would act), technical assessment, or a combination.

3. Develop questions and a scoring rubric

Write clear questions mapped to competencies. Favor open-ended behavioral prompts (for example, ask for a specific project example using the STAR technique: Situation, Task, Action, Result). Create a simple scoring scale (e.g., 1–5) and define what performance at each level looks like for each competency. Share the rubric with interviewers in advance.

4. Plan logistics and interviewer roles

Schedule appropriate time, confirm technology for remote interviews, and prepare materials (resume, job brief, rubric). If using a panel, assign roles—primary interviewer, technical reviewer, note-taker—so the interview flows and documentation remains consistent. Provide basic interviewer training on asking follow-up questions and avoiding leading prompts.

5. Conduct the interview professionally

Start by explaining the agenda, estimated duration, and next steps to set expectations. Use the predetermined question set, probe for details without interrupting, and take structured notes tied to competencies. Allow time for candidate questions and assess both answers and candidate engagement. Close by outlining the timeline for decisions.

6. Evaluate objectively and compare candidates

Immediately after each interview, complete the scoring rubric while impressions are fresh. Compare candidate scores against the job’s defined criteria rather than against each other informally. Document strengths, gaps, and any clarifying questions for reference checks. Where possible, aggregate scores from multiple interviewers to reduce single-rater bias.

7. Legal, fairness, and accessibility considerations

Be familiar with applicable employment laws and non-discrimination rules. Avoid questions about protected characteristics (age, race, religion, disability, family status) and focus on job-related competencies. Offer reasonable accommodations for candidates with disabilities and ensure interview settings—virtual or in-person—are accessible. For guidance on discrimination and equal employment rules, consult reputable regulators such as the U.S. Equal Employment Opportunity Commission (EEOC): U.S. Equal Employment Opportunity Commission (EEOC).

8. Remote and video interview tips

Test technology in advance, choose a quiet and well-lit location, and share instructions with the candidate on how the session will run. Observe nonverbal cues while recognizing that video can limit full body language signals; rely more on clear, competency-based responses and consistent follow-ups.

9. Common pitfalls to avoid

Beware of confirmation bias (seeking information that supports an early impression), halo/horns effects (one trait overshadowing others), and unstructured conversations that make comparisons difficult. Do not skip reference checks when appropriate, and ensure documentation supports hiring decisions.

Maintaining quality and improving the process

Collect feedback and iterate

Track hiring outcomes and gather interviewer and candidate feedback to refine question sets and rubrics. Periodic calibration sessions among interviewers help keep standards aligned and reduce drift in scoring over time. Training in structured interviewing and unconscious bias awareness improves fairness and predictive validity.

Recordkeeping and confidentiality

Store interview notes and evaluations according to organizational policy and data protection laws. Maintain confidentiality of candidate information and limit access to decision-makers and HR staff.

How to conduct an interview?

Follow a structured, transparent process: define competencies, use consistent questions, score answers with a rubric, document decisions, and comply with legal and accessibility requirements. Emphasize evidence-based answers and reduce subjective impressions through multiple raters and calibration.

What are effective types of interview questions?

Behavioral questions (past behavior), situational questions (hypothetical scenarios), technical problems, and work-sample tasks are effective when tied to job duties. Use follow-ups to elicit specifics about actions and outcomes.

How should interviewer bias be managed?

Use structured interviews, standardized rubrics, multiple interviewers, and calibration meetings. Training on unconscious bias and careful documentation of scoring rationale helps reduce subjective influences.

When should assessments or reference checks be used?

Use assessments to validate specific skills not easily judged in conversation. Conduct reference checks to confirm past performance and verify areas of concern revealed during interviews, following organizational policies and consent practices.
