Discover What a Candidate Can Really Do

By Don Georgevich

Phase Three of the Scientific Hiring Method: Discovery

The purpose of candidate evaluation is not to confirm your first impression. It is to gather enough job-related evidence to understand what the person can really do.

A candidate can look convincing long before the company knows whether they can perform the work. A polished résumé creates one impression. A strong first conversation creates another. Confidence, familiarity, and personal chemistry can make the answer feel obvious before the evidence is complete.

Discovery slows that rush to judgment. Each stage is designed to answer a different question, and no single stage is expected to carry the entire decision.

The résumé is a starting point, not proof

A résumé shows what the candidate chose to present. It may reveal career patterns, scope, progression, relevant work, and claims worth exploring. It does not show the full context behind those claims or prove that the candidate personally produced the result.

Use résumé screening to identify evidence that deserves further examination, missing information that matters, and basic requirements that can be checked consistently. Do not turn titles, employer names, or writing polish into automatic proof of capability.

The first screen should protect everyone’s time

Not every applicant deserves a full interview, but every screening decision should have a job-related reason.

The Candidate Screening guide explains how to apply the role standard before personal preference takes over. The screen should decide whether there is enough relevant evidence to continue, not whether the candidate already feels like the final hire.

A short phone screening interview can then confirm practical requirements, clarify the candidate’s understanding of the work, examine important résumé claims, and determine whether a deeper evaluation is worthwhile.

A structured interview makes evidence comparable

Unstructured interviews often follow the interests of the interviewer and the direction of the conversation. One candidate may be questioned deeply about a failure, while another is allowed to spend most of the meeting discussing strengths.

OPM defines a structured interview as an assessment method that measures job-related competencies through a standardized questioning and scoring process. Candidates are asked predetermined questions and evaluated against the same standards, which improves consistency and comparability. See OPM’s Structured Interviews guidance.

The Structured Interview section will show how to connect questions to the job scorecard, probe for complete evidence, and have interviewers record their judgment before the group discussion begins.

Work samples reveal how the person approaches real work

A candidate may describe strong work without showing how they think, decide, communicate, or handle constraints.

A realistic work sample test gives the person a fair opportunity to perform a small version of work that matters in the role. OPM describes work samples as tasks or activities that mirror work performed on the job. The exercise should be relevant, reasonably limited, and evaluated against a standard established before candidates complete it. See OPM’s Work Samples and Simulations guidance.

The goal is not to obtain free work. It is to see evidence that cannot be produced through conversation alone.

References verify patterns, not merely employment dates

Reference checks should return to the claims, strengths, and risks identified earlier. Ask people who observed the candidate’s work about the same outcomes and behaviors the company is evaluating.

A useful reference-checking process does not ask only whether the person is eligible for rehire. It tests whether the patterns described by the candidate are visible to other people who worked closely with them.

Each stage should earn the next one

The process should become more demanding as the evidence becomes stronger.

Early stages should be inexpensive and focused. They remove candidates who do not meet real requirements and clarify whether enough evidence exists to continue. Later stages should examine the most important outcomes, unresolved risks, and work that is difficult to judge through earlier methods.

This prevents the company from giving every applicant a long process while also preventing one attractive résumé or pleasant conversation from becoming the entire case for hiring.

Discovery begins with the standard set in Phase One

Candidate evaluation should not invent new criteria. It should gather evidence against the outcomes and capabilities already written into the Job Scorecard and Hiring Criteria.

OPM’s assessment-strategy guidance recommends basing selection tools on an up-to-date job analysis and using evidence that connects assessment performance with job performance. The tools chosen should match the competencies and work being evaluated. See OPM’s Designing an Assessment Strategy.

When evaluation stages are disconnected from the role standard, the company collects a great deal of information without knowing what should control the decision.

Good evidence is specific, relevant, and tested

A strong example explains the situation, the candidate’s actual responsibility, the actions they personally took, the decisions they made, the result, and what they learned. It should remain credible when the interviewer asks for detail.

Relevance matters as much as impressiveness. A major accomplishment in a very different environment may reveal useful capability, but the team still needs to understand whether the person can succeed under the authority, resources, pace, and constraints of the current role.

Important evidence should be tested more than once. A leadership claim may appear in the interview, become visible in the work sample, and be confirmed through references. Agreement across independent sources gives the decision more support.

Do not collect information you should not use

Candidate evaluation should remain focused on the work. Do not search for or make decisions from protected personal information, medical history, family circumstances, age assumptions, or other information unrelated to job performance.

The EEOC advises employers to ensure hiring decisions are not based on protected characteristics and that tests or selection procedures are job-related and appropriate for their purpose. See the EEOC’s small-business hiring guidance and Employment Tests and Selection Procedures.

The Phase Three path

1. Decide who deserves more time

Begin with Candidate Screening, then use Resume Screening and Evaluation, the Phone Screening Interview, and Phone Screening Questions.

2. Conduct interviews that produce comparable evidence

Use How to Conduct a Job Interview, the complete Structured Interview method, and Structured Interview Questions. The comparison of Structured and Unstructured Interviews explains why the standard matters.

3. Build the right question set

Choose from Interview Questions to Ask Candidates and the deeper guide to Behavioral Interview Questions.

4. Grade and record the evidence

Use the Interview Rubric, Interview Scorecard, and practical Interview Scorecard Template.

5. Let the candidate demonstrate the work

Use a Candidate Test Drive to observe how the person handles a short, realistic work sample before you hire.

6. Verify the patterns

Use Reference Checking and focused Reference Check Questions to confirm important claims, add context, and resolve the risks found earlier.

What this phase should produce

By the end of Discovery, the company should be able to explain what each candidate proved, which evidence is weak or missing, where sources agree or conflict, and which risks remain unresolved.

The purpose is not certainty. No hiring process can create that. The purpose is to replace a vague feeling with a body of evidence strong enough to support the decision that follows.
