Interview Techniques and Best Practices: A Comprehensive Guide for aPHR Exam Preparation
Introduction
Interview Techniques and Best Practices is a critical topic within the Talent Acquisition competency area of the aPHR (Associate Professional in Human Resources) certification exam. Mastering this subject is essential not only for passing the exam but also for building a strong foundation in HR practice. This guide covers why interview techniques matter, what they entail, how they work in practice, and how to approach exam questions on this topic.
Why Interview Techniques and Best Practices Are Important
Interviewing is one of the most critical steps in the talent acquisition process. Effective interview techniques directly impact an organization's ability to:
• Select the best candidates: Well-structured interviews improve the quality of hiring decisions and reduce the risk of bad hires, which can cost organizations significant time and money.
• Ensure legal compliance: Proper interviewing techniques help organizations avoid discriminatory practices and ensure compliance with federal and state employment laws, including Title VII of the Civil Rights Act, the Americans with Disabilities Act (ADA), and the Age Discrimination in Employment Act (ADEA).
• Reduce bias: Structured and standardized interview processes minimize unconscious bias and promote fairness in the selection process.
• Enhance candidate experience: Professional and well-organized interviews reflect positively on the employer brand and contribute to a positive candidate experience.
• Improve retention: Hiring the right person for the right role through effective interviewing leads to better job fit, higher satisfaction, and lower turnover.
What Are Interview Techniques and Best Practices?
Interview techniques refer to the various methods, formats, and strategies used by HR professionals and hiring managers to evaluate candidates during the selection process. Best practices represent the most effective and legally defensible approaches to conducting interviews.
Types of Interviews:
1. Structured Interviews: All candidates are asked the same predetermined set of questions in the same order. Responses are evaluated using a standardized rating scale. This is considered the gold standard in interviewing because it provides the highest level of reliability and validity.
2. Unstructured Interviews: Questions are not predetermined and may vary between candidates. While they allow for more conversational flow, they are less reliable, more prone to bias, and harder to defend legally.
3. Semi-Structured Interviews: A hybrid approach that uses a core set of predetermined questions while allowing flexibility for follow-up questions based on candidate responses.
4. Behavioral Interviews: Based on the premise that past behavior is the best predictor of future performance. Questions typically begin with phrases like "Tell me about a time when..." or "Describe a situation where..." Candidates are expected to provide specific examples using the STAR method (Situation, Task, Action, Result).
5. Situational Interviews: Present candidates with hypothetical scenarios related to the job and ask how they would handle them. These assess problem-solving ability and judgment.
6. Panel Interviews: Multiple interviewers assess the candidate simultaneously. This approach reduces individual bias and provides diverse perspectives on the candidate.
7. Phone/Video Screening Interviews: Used as a preliminary step to evaluate basic qualifications, communication skills, and cultural fit before inviting candidates for in-person interviews.
8. Group Interviews: Multiple candidates are interviewed simultaneously. This can be useful for observing interpersonal skills, teamwork, and leadership in real time.
9. Stress Interviews: Intentionally create a high-pressure environment to see how candidates handle stress. These are controversial and should be used cautiously.
10. Sequential (Serial) Interviews: The candidate meets with multiple interviewers one after another, each conducting a separate interview.
Key Interview Best Practices:
• Job Analysis Foundation: All interview questions should be derived from a thorough job analysis and linked directly to the essential functions and competencies of the position.
• Consistency: Ask the same core questions to all candidates for a given position to ensure fairness and comparability.
• Standardized Evaluation Criteria: Use rating scales and scoring rubrics to evaluate responses objectively.
• Legal Compliance: Avoid questions related to protected characteristics such as age, race, religion, national origin, gender, marital status, disability, pregnancy, or genetic information.
• Documentation: Take detailed, job-related notes during each interview to support hiring decisions and provide evidence of a fair process.
• Training: All interviewers should receive training on proper interview techniques, legal requirements, and recognizing unconscious bias.
• Multiple Interviewers: Using more than one interviewer increases objectivity and reduces the impact of individual biases.
• Realistic Job Preview (RJP): Provide candidates with honest information about the job, including both positive and challenging aspects, to set accurate expectations.
How the Interview Process Works
The interview process typically follows these steps:
Step 1: Preparation
• Review the job description and person specification
• Develop interview questions based on job analysis
• Create a scoring rubric or evaluation form
• Schedule interviews and notify all stakeholders
• Review candidate resumes and application materials
Step 2: Opening the Interview
• Greet the candidate warmly and establish rapport
• Explain the interview format, timeline, and process
• Provide a brief overview of the organization and the role
Step 3: Conducting the Interview
• Ask job-related questions in a consistent order
• Use behavioral and situational questions to assess competencies
• Listen actively and take notes
• Allow the candidate to ask questions
• Avoid leading questions or providing cues about desired answers
Step 4: Closing the Interview
• Thank the candidate for their time
• Explain the next steps and timeline for the decision
• Answer any remaining questions the candidate may have
Step 5: Evaluation and Decision
• Complete the evaluation form immediately after the interview
• Compare candidate scores objectively using the standardized criteria
• Discuss evaluations with other interviewers (if applicable)
• Make a hiring recommendation based on job-related criteria
• Document the rationale for the selection decision
Legal Considerations in Interviewing
HR professionals must be acutely aware of what is and is not permissible during interviews:
Questions to Avoid (Illegal or Inappropriate):
• "How old are you?" or "When did you graduate from high school?"
• "Are you married?" or "Do you plan to have children?"
• "What is your religion?" or "Do you observe any religious holidays?"
• "Where were you born?" or "What is your native language?"
• "Do you have any disabilities?"
• "Have you ever been arrested?" (Note: asking about convictions may be permissible depending on jurisdiction and relevance to the job)
Acceptable Alternatives:
• "Are you legally authorized to work in the United States?"
• "Can you perform the essential functions of this job with or without reasonable accommodation?"
• "Are you available to work the required schedule for this position?"
• "Do you have any convictions that are directly related to the duties of this position?" (where legally permissible)
Key Concepts to Remember for the aPHR Exam
• Reliability refers to the consistency of the interview process — structured interviews are more reliable than unstructured ones.
• Validity refers to how well the interview predicts actual job performance — behavioral and situational interviews tend to have higher predictive validity.
• Halo Effect: When an interviewer allows one positive characteristic to influence the overall assessment of the candidate.
• Horn Effect: The opposite of the halo effect — one negative characteristic unduly influences the overall evaluation.
• Contrast Effect: Evaluating a candidate relative to the previous candidate rather than against objective criteria.
• First Impression Bias (Primacy Effect): Making a judgment about a candidate within the first few minutes of the interview.
• Similar-to-Me Bias: Favoring candidates who share similar backgrounds, interests, or characteristics with the interviewer.
• Central Tendency: Rating all candidates as average to avoid making definitive judgments.
• Leniency/Strictness Bias: Consistently rating candidates too high or too low.
• Recency Effect: Giving more weight to information learned at the end of the interview.
Exam Tips: Answering Questions on Interview Techniques and Best Practices
1. Always favor structured over unstructured interviews: When an exam question asks which type of interview is most reliable, valid, or legally defensible, the answer is almost always the structured interview. Remember that structured interviews with standardized questions and scoring rubrics are the best practice.
2. Behavioral interviews predict future performance: The aPHR exam frequently tests the concept that past behavior is the best predictor of future behavior. If a question asks about the most effective way to assess how a candidate will perform, behavioral interviewing is typically the correct answer.
3. Know the difference between behavioral and situational questions: Behavioral questions ask about past experiences ("Tell me about a time..."), while situational questions present hypothetical scenarios ("What would you do if..."). Both are valid techniques, but they serve slightly different purposes.
4. Focus on legal compliance: Many exam questions test your knowledge of what questions are and are not permissible. Remember the key rule: all interview questions must be job-related and consistent with business necessity. If a question asks whether a particular interview question is appropriate, evaluate whether it relates to a protected characteristic.
5. Understand interviewer biases: Be prepared to identify different types of bias (halo effect, horn effect, contrast effect, similar-to-me bias, etc.) from scenario-based descriptions. The exam may present a situation and ask you to identify which bias is occurring.
6. Job analysis is the foundation: When in doubt, remember that all effective interview processes begin with a thorough job analysis. Questions should be based on the essential functions and required competencies identified in the job analysis.
7. Documentation is critical: If an exam question asks about best practices after an interview, choosing the option that involves documenting observations, scores, and rationale for decisions is typically correct.
8. Training interviewers matters: The exam may test whether you understand the importance of training all interviewers. Untrained interviewers are more likely to ask inappropriate questions, exhibit bias, and make inconsistent evaluations.
9. Use the process of elimination: For multiple-choice questions, eliminate answers that involve illegal questions, unstructured approaches, or actions that introduce bias. The best answer is usually the one that is most standardized, job-related, and legally compliant.
10. Think like an HR professional, not a hiring manager: The aPHR exam tests your knowledge of HR best practices. Even if a particular approach might seem practical or efficient, always choose the answer that reflects best practices in terms of fairness, consistency, legal compliance, and validity.
11. Remember the STAR method: The Situation, Task, Action, Result framework is closely associated with behavioral interviewing. If the exam references this framework, connect it to behavioral interview techniques.
12. Panel interviews reduce bias: If a question asks about ways to reduce individual interviewer bias, panel interviews and multiple interviewers are strong answer choices.
Practice Scenario
Question: An HR professional is designing an interview process for a customer service representative position. Which approach would be most effective in predicting job performance?
The best answer would involve: conducting a structured behavioral interview with questions derived from a job analysis, using a standardized scoring rubric, and having trained interviewers evaluate candidates consistently.
Summary
Interview techniques and best practices form a cornerstone of effective talent acquisition. For the aPHR exam, focus on understanding the types of interviews (especially structured and behavioral), legal compliance requirements, common interviewer biases, and the importance of standardization and documentation. Always anchor your answers in the principles of job-relatedness, fairness, consistency, and legal defensibility. By mastering these concepts, you will be well-prepared to answer any exam question on this topic confidently and accurately.
