CODESP Interviewing Techniques and Methods 4 — Questions and Answers
Question 1: What is the primary purpose of a 'benchmark' or 'anchor' response in a structured oral interview?
- To provide interviewers with a model answer that defines each point on the scoring scale (Correct answer)
- To give candidates an example of how to answer questions
- To document the interviewer's personal expectations
- To set the minimum passing score for the exam
Correct answer: To provide interviewers with a model answer that defines each point on the scoring scale
Benchmark or anchor responses give interviewers concrete examples of what a 1-point, 3-point, or 5-point answer looks like, reducing subjectivity in scoring.
Question 2: A candidate makes an offhand comment revealing they have a young child, and the interviewer unconsciously rates them lower on 'reliability.' This is an example of:
- Contrast effect
- Attribution error
- Stereotyping bias (Correct answer)
- Central tendency error
Correct answer: Stereotyping bias
Stereotyping bias occurs when an interviewer applies generalized assumptions about a demographic group to an individual candidate.
Question 3: Which validation strategy is most appropriate when a job analysis reveals that interview questions measure the same constructs as a written test?
- Criterion-related validity study
- Convergent construct validity analysis (Correct answer)
- Face validity review
- Predictive validity study with a future cohort
Correct answer: Convergent construct validity analysis
Convergent construct validity examines whether two measures that theoretically assess the same construct correlate with each other as expected.
Question 4: In public sector merit-based hiring, oral interviews are most commonly used at which stage of the selection process?
- As the sole selection device before a written exam
- After an initial screening step such as a written exam or minimum qualifications review (Correct answer)
- Before any application materials are reviewed
- Only for internal promotions, not entry-level hiring
Correct answer: After an initial screening step such as a written exam or minimum qualifications review
Oral interviews in public sector agencies typically follow a written exam or application screening to ensure only qualified candidates advance to the more resource-intensive interview step.
Question 5: Which interviewer behavior is most likely to introduce contamination into scoring?
- Taking structured notes during each response
- Discussing candidate responses with other panelists before scoring independently (Correct answer)
- Using pre-established scoring anchors
- Asking all candidates identical questions in the same order
Correct answer: Discussing candidate responses with other panelists before scoring independently
Discussing responses before independent scoring allows one panelist's opinion to anchor or contaminate the ratings of others, undermining inter-rater independence.
Question 6: What does content validity mean in the context of an interview?
- The interview predicts job performance better than chance
- The interview questions adequately represent the KSAs required for the job (Correct answer)
- The interview scores correlate with supervisor ratings
- The interview is perceived by candidates as fair and relevant
Correct answer: The interview questions adequately represent the KSAs required for the job
Content validity refers to the degree to which interview questions comprehensively sample the knowledge, skills, and abilities identified in the job analysis.
Question 7: An interviewer rates all candidates near the midpoint of the scale, avoiding high and low scores. This error is called:
- Halo effect
- Leniency error
- Central tendency error (Correct answer)
- Contrast effect
Correct answer: Central tendency error
Central tendency error occurs when raters avoid extreme ratings and cluster all scores near the middle of the scale, reducing the discriminating power of the interview.
