KSA Interview Techniques & Performance Measurement 3 — Questions and Answers
Question 1: Situational interview questions differ from behavioral interview questions in that they:
- Ask about past job experience exclusively
- Present hypothetical scenarios and ask what the candidate would do (Correct answer)
- Require candidates to bring portfolio samples
- Are only used in technical assessments
Correct answer: Present hypothetical scenarios and ask what the candidate would do
Situational questions pose future-oriented hypothetical scenarios, while behavioral questions focus on past actual experiences.
Question 2: The '4/5ths rule' in KSA assessment is used to detect:
- Test fatigue in long assessments
- Adverse impact against a protected group (Correct answer)
- Excessive leniency in scoring
- Random error in performance ratings
Correct answer: Adverse impact against a protected group
The 4/5ths (80%) rule flags adverse impact when the selection rate of a protected group is less than 80% of the rate for the highest-selected group.
Question 3: Which type of question is generally prohibited in US employment interviews because it may reveal protected class membership?
- Tell me about a time you missed a deadline.
- What is your country of origin? (Correct answer)
- Describe your biggest professional achievement.
- How do you handle competing priorities?
Correct answer: What is your country of origin?
Asking about national origin can reveal protected class status and violates EEO guidelines, exposing the employer to discrimination claims.
Question 4: A KSA assessor builds a scoring guide where each KSA is weighted differently based on its importance to the job. This approach is called:
- Compensatory scoring model
- Multiple cutoff model
- Weighted scoring rubric (Correct answer)
- Holistic assessment matrix
Correct answer: Weighted scoring rubric
A weighted scoring rubric assigns different point values to KSAs based on their relative importance to job performance, allowing critical skills to influence the total score more.
Question 5: When an interviewer forms an overall impression of a candidate based on a single outstanding trait (positive or negative), this rating error is called:
- Horn effect only
- Halo or horn effect (Correct answer)
- Primacy bias
- Attribution error
Correct answer: Halo or horn effect
The halo effect occurs when one positive trait inflates all ratings, while the horn effect occurs when one negative trait depresses all ratings—both stem from the same cognitive distortion.
Question 6: In a panel interview designed to measure KSAs, best practice requires that panelists:
- Discuss candidate impressions before scoring
- Score candidates independently before group discussion (Correct answer)
- Rotate who asks questions randomly each round
- Allow candidates to choose which panelist to address
Correct answer: Score candidates independently before group discussion
Independent scoring before group discussion prevents groupthink and anchoring bias, preserving the integrity of each panelist's assessment.
Question 7: A performance measurement system that sets specific, measurable targets agreed upon between manager and employee at the start of a period, then evaluates achievement at the end, is called:
- Critical incident method
- Management by Objectives (MBO) (Correct answer)
- Graphic rating scale
- Paired comparison method
Correct answer: Management by Objectives (MBO)
MBO establishes mutually agreed-upon objectives at the outset and evaluates employee performance based on the degree to which those objectives were met.
