Traditional hiring methods typically focus on how candidates present themselves, the appeal of technical phrases in their résumés, and the interviewer’s immediate personal affinity. However, modern human resources management and industrial psychology research has proven that unstructured, intuitive interviews of this kind are extremely poor at predicting job performance. Behavioral or competency-based interviews, by contrast, are based on the principle that a candidate’s concrete past performance and behavior are the strongest and most reliable predictors of future job success.

Large-scale meta-analysis studies conducted by Schmidt and Hunter, covering more than 86,000 hiring records, clearly reveal the gulf between the validity coefficients of different types of interviews in predicting job success. Unstructured interviews offer predictive validity close to the level of random selection, at 0.20, while competency-based structured interviews more than double this rate, bringing it to 0.51. When the process is supported by Behaviorally Anchored Rating Scales (BARS), the validity coefficient reaches the highest scientific level, at 0.57.

What Is a Competency-Based Interview and Why Does It Matter?

A competency-based interview is a scientific assessment methodology that measures a candidate’s core behavioral, cognitive, and interpersonal competencies for a role through their past experience, using standardized questions for every candidate.

How Is Korn Ferry and SHRM Competency Modeling Done?

Korn Ferry and SHRM competency modeling is a corporate design process that standardizes human resources planning by dividing the critical work behaviors expected of roles in modern organizations into rational, measurable categories.

In U.S.-based human resources standards, strategic competency design is based on two main schools of thought: the Korn Ferry Leadership Architect (KFLA) and the Society for Human Resource Management (SHRM) Competency Model. The SHRM approach emphasizes that human resources professionals should be business partners who shape organizational strategy, not merely administer processes. In this model, competencies are grouped into three core clusters—Leadership, Interpersonal, and Business—and aligned directly with organizational goals.

The Korn Ferry Leadership Architect (KFLA), in turn, classifies 38 behavioral competencies with proven validity worldwide under four factors: Thought, Results, People, and Self. One of the most critical and distinctive features of this model is the “Developmental Difficulty Rating” parameter for each competency at different organizational levels. These ratings, which range from 1 (easiest) to 5 (most difficult), indicate how much time, effort, and developmental flexibility a candidate will need to acquire and demonstrate the relevant competency on the job.

Korn Ferry research shows that competencies explain more performance variation than a candidate’s past experience, personal motivation, or educational background. This reinforces the strategic importance of measuring behavioral dimensions alongside technical skills in hiring decisions. In global leadership models, leaders’ ability to foster high engagement within their teams, reduce turnover, and create a sustainable performance climate depends directly on accurately assessing specific people-focused competencies such as “Builds Effective Teams,” “Instills Trust,” and “Develops Talent” during interviews.

What Are Behaviorally Anchored Rating Scales (BARS)?

Behaviorally Anchored Rating Scales (BARS) are a systematic assessment method that scores a candidate’s interview responses by matching them with concrete, observable behavioral anchors established in advance through job analysis, rather than relying on subjective judgments.

One of the most common errors assessors make in recruitment and selection—the leniency bias—and subjective assessment criteria can be minimized through the use of Behaviorally Anchored Rating Scales (BARS). Establishing a BARS framework involves a five-stage methodological process led by the human resources department and requiring the active participation of business units:

1. Establishing the Governance Team: Support from senior management is secured to ensure that the process does not remain merely a human resources initiative and is aligned with the organization’s strategic goals.
2. Identifying Subject Matter Experts (SMEs): The first expert group is formed from senior employees and managers who know the relevant job role best.
3. Identifying Behaviors Using the Critical Incident Technique (CIT): Experts document work behaviors observed in the role that were exceptionally effective and exceptionally ineffective (critical incidents).
4. Defining Performance Dimensions: The raw behavioral statements collected are analyzed and grouped under shared competency dimensions such as “Collaboration,” “Conflict Management,” or “Customer Focus.”
5. Retranslation and Scaling: A second independent expert group rematches the documented concrete behaviors with the dimensions to which they belong and rates the effectiveness of each behavior on a scale from 1 to 5, finalizing the scale’s anchors.

“Collaboration” (Collaborates) Competency BARS Rubric

This dimension assesses how the candidate builds partnerships across the organization to achieve shared goals and fosters a culture of working together.

“Taking Initiative and Proactive Problem-Solving” Competency BARS Rubric

This dimension analyzes how the candidate takes action to address disruptions in work processes and create value without receiving formal instructions.

How Do You Design Interview Questions Using STAR and EAR Methodologies?

STAR and EAR interview question design is a structured question-design model that examines a candidate’s past situation (Situation), the task they took on (Task), the actions they performed (Action), and the results they achieved (Result) using chronological, measurable data.

The assessment process should be treated not as a “highlight reel” of the candidate’s career, but like an analysis of the raw game footage; what matters here is the chronological consistency of decisions, not flashy statements.

How Do You Manage Candidate Scorecards and Calibration?

A candidate scorecard is an HR process document that standardizes a candidate’s performance in weighted, role-specific competency areas using a concrete BARS scale after the interview and ensures consistency in decisions among interviewers.

To maximize hiring accuracy, six golden rules must be followed meticulously when using a scorecard:

• The 30-Minute Rule: Interviewers should complete the candidate scorecard within the first 30 minutes after the interview ends. As time passes, candidates’ specific statements are forgotten, and assessors revert to general impressions and biases.
• Independent Scoring: Assessors should enter their scores and written rationale for the candidate into the system before the joint calibration meeting (debrief). This prevents dominant figures within the team from influencing other interviewers (groupthink).
• Independent Assessment of Competencies: Each competency should be scored separately. Strong performance in one area should not mask shortcomings in others (preventing the halo effect).
• Weighting System: Competencies that are critical to the role should be weighted more heavily than less critical competencies.
• The Zero-Score Safety Valve: If the interview did not include enough questions about a particular competency area to obtain concrete evidence, the interviewer should select “0 - Insufficient Information” rather than assign an estimated score.
• Quarterly Calibration Sessions: The hiring team and department managers should meet quarterly to score shared interview recordings or mock candidates and measure consistency between assessors.
