Title: The Situational Interview
1The Situational Interview
2Definition
- Job-related situational questions
- Situations are specific on-the-job activities
- Applicants put in hypothetical situations
- Questions can refer to past experience or future
intentions - Differs from structured format by benchmarking
applicant responses

Redefinition of Selection Tool A valid test
cannot be developed until the organization agrees
upon an acceptable definition (measure) of
employee behavior. Latham Wexley, 1982
Workforce Prediction Quality of workforce will
deteriorate Dyer, 1981
Legal Issues Selection Process Dilemma Griggs vs.
Duke Power, 1971
4Research Literature
- Latham, Saari, Pursell, Campion, 1980
- Examined reliability and validity of situational
interview by conducting three studies - Study 1 entry-level position, Study 2
first-line supervisory position, Study 3
concurrent predictive validity - Results for Study 1 Interview scores were
significantly correlated with every performance
criterion including the overall global rating - Results for Study 2 Interview scores correlated
significantly with three of four criteria
safety, work habits, org commitment - Results for Study 3 Interview scores
significantly correlated with composite job
performance scores, even for women and black
employees
5Research Literature
- Conclusions of Latham et al. (1980)
- Intentions correlate with behavior
- Comprehensive job analysis reflect content
validity - Interviewee motivation influenced by face
validity - Inter-rater reliability high because interviewers
themselves developed scoring key - Emphasis on critical behaviors rather than traits
- Past behavior based items could lessen dishonest
responses, it can be verified by previous
employer. However, adverse impact must be kept in
check
6Research Literature
- Pulakos Schmitt, 1995
- Compared validities of experience-based (past
performance) questions and situational (future
intentions) questions - Results Past performance is better predictor of
job performance - Lack of Validity for Situational Items Attributed
to - Responses were evaluated at end of interview. It
is necessary to make the ratings immediately - Prior studies indicate that situational
interviews involve lower-level jobs. In this
study, the job was complex and demanding - Major conclusion was that interviews result in
lower levels of adverse impact because they
measure cognitive as well as non-cognitive
performance dimensions
7Research Literature
- Maurer Fay, 1988
- Two hypotheses Rater training
Inter-rater agreement - Situational
Inter-rater agreement - Interpretation of results Situational interviews
are more effective in producing higher
inter-rater agreement, even with little or no
training, because of specific rating scales - There was so significant main effect of training
- Situational interview is more cost-effective
strategy in comparison with conventional
structured interview
8Critical Incident Technique
- Was first developed and used by John Flanagan and
his students at the University of Pittsburgh in
the late 1940s and early 1950s - Used to identify job behaviors that differentiate
successful performance from unsuccessful
performance - Can be useful in job analysis as well as training
and performance appraisal - The development of the graduate situational
interview was based on this technique
9Critical Incident Development
- Critical incidents were identified by reviewing
the job analysis (CMQ) - Behaviors that could exemplify either good or
poor behaviors of graduate students were chosen - Fourteen job dimensions were identified
- Prioritizing Leadership
- Stress management Ethics
- Ability to work with others Public speaking
- Receiving feedback Altruism
- Self Assessment Diversity
- Decision making Retention
- Group involvement
- Participation
10Development of Situational Interview Questions
- The critical incidents were used to form the
questions to be asked in the situational
interview - The beginning of each question stem entailed a
description of a circumstance involving a
critical incident - Example Critical Incident Decision Making
- Example You are placed at a company in which
your supervisor is critical and provides no
direction to complete a task - The questions ended with a general proposition
- Example How would you handle this situation?
- Seventeen questions were written using this
format - Each critical incident that we identified had a
corresponding question - Two of the critical incidents had more that one
corresponding question, namely stress management
and ethics
11BARS Development
- To facilitate the scoring process a behaviorally
anchored rating scale was developed for each
question - The behavioral scales were developed by
brainstorming and determining KSA relevance and
importance as rated by SMEs (job incumbents) - Our anticipation of the responses that we would
receive was used to develop a five point scale - The five point scales included examples of high,
average and low responses - The examples that we agreed represented high,
average and low responses were used as behaviors
on the scale
12Example
- 5 Applicant tries to talk to the boss
- 4 Applicant tries to set own goals and
direction no resolve of conflict. - 3 Applicant says nothing.
- 2 Applicant complains, does not start the
job until the issue is addressed. - 1 Applicant leaves the job/talks to boss in
a negative fashion.
13Focus Groups
- Our questions and behavioral scales were
presented to a focus group - The focus group (subject matter experts)
recommended the following - - add multitasks to the scales
- - reword ambiguous and vague questions
- - make sure that each question corresponds to
the critical incident it is describing in a
situation
14Scoring of the Situational Interview
- Each response on the behavioral scale had a
corresponding score - Scores were rated from one to five
- - a 1 or 2 represented a low response
- - a 3 represented an average response
- - a 4 or 5 represented a high response
- The interviewers choose the response that best
represents the interviewees answer - A total score for the interview can be obtained
by summing the ratings for each question
15Development of Cutoff Score
- The Ebel method was used to determine the cutoff
score - - rate each item (1-5)
- - determine the percentage of items a minimally
qualified candidate would respond to correctly (a
correct response to each item represented a score
of 3 or more) - - multiply this percentage by the number of
items - (3 x 17 51)
- - the cutoff score becomes 51 for the
situational interview
16Administration
- Participants 30 I/O graduate students
- Two groups of raters 3 and 2
- Selection Tool was administered twice over a 2
week period. - The Tool was administered in a classroom setting
with other selection tests being administered at
the same time.
17Possible Threats To Validity
- Random Error
- Noise/Disruption Effects
- Exposure to test questions before administration
- Fakeablity
- Rater effects(Halo, Contrasts, Leniency Effects)

21Near Future
- Standardize scores
- Reliability and more validity analysis
- Analyze individual questions
22Distant Future
- How can we modify the interview to make it a
better instrument for selecting graduate
students? - separate information gathering and evaluation,
evaluate after gathering - modify behavioral anchors
- re-categorize questions so that questions which
co-vary are in the same category
