Using Assessments, Tests, and Simulations in Hiring: When and Why They Matter

Interviews are powerful, but they can’t tell you everything. When you’re hiring for high-impact roles—or when you’re trying to narrow a large pool of candidates—additional assessment tools can give you deeper insights and greater confidence in your hiring decisions.

Here’s how to use assessments and simulations effectively, and what to watch out for.

Why Go Beyond the Interview?

While interviews give you a feel for personality and communication style, they don’t always reveal:

Problem-solving ability

Job-specific technical skills

Long-term fit for the role or team

Personality traits and cognitive strengths

Assessments and simulations provide objective, standardized ways to gather this information—especially when structured correctly and aligned with job requirements.

Common Types of Assessments

1. Web-Based or Traditional Tests
These measure traits, skills, or aptitudes, and are often used early in the selection process.

Examples include:

Cognitive ability tests (general intelligence, verbal reasoning, etc.)

Personality tests (sociability, emotional stability, drive)

Technical knowledge tests (e.g. hydraulics, software, electronics)

Basic aptitude tests (math, reading, spatial reasoning)

Advantages:

Inexpensive and easy to administer

Consistent scoring across all candidates

Disadvantages:

Legal risk if not clearly job-related

Requires interpretation by trained professionals

Poor alignment = irrelevant results

Best Practice: Always ensure the assessment aligns with the role’s core competencies and is validated for your industry or job type.

Simulations: Real Work, Real Results

Simulations place candidates in scenarios similar to the job they’d perform. These are often used for leadership roles, technical roles, or restructured environments.

Types of simulations include:

In-basket exercises (responding to mock emails, reports, or priorities)

Group discussions (problem-solving in a team setting)

Analysis exercises (reviewing data to make recommendations)

Role-playing interactions (handling a conflict or sales pitch)

Advantages:

Provides a realistic view of candidate performance

Yields high-quality, behaviour-based data

Gives candidates insight into the role

Disadvantages:

Time-consuming and costly to develop

Requires trained assessors to score fairly

When to Use These Tools

Consider adding assessments or simulations when:

You’re hiring for high-impact, leadership, or technical roles

The job is complex or newly created

You want to reduce reliance on interviews alone

You’re narrowing a large candidate pool efficiently

You’ve had previous hiring misses and need more data

Final Thought

Assessments and simulations aren’t meant to replace interviews—they’re meant to enhance them. Used thoughtfully, they can increase objectivity, improve hiring accuracy, and help you select candidates who are truly set up to thrive in the role.
