How to Hire a Great Software Engineer

Problem-solving, coding judgment, and disciplined work habits. Here is the evidence-based way to find the top 5% — before the interview.

What actually predicts success

For this role, the traits that separate top performers are:

• Logical reasoning
• Software concepts
• Numerical ability
• Conscientiousness

Resumes can't measure any of these. A structured assessment battery can.

The recommended test battery (23 minutes)

• Logical Reasoning — Fluid problem-solving with patterns and rules — culture-fair and language-light.
• Software Concepts — Practical programming judgment beyond syntax — data structures, debugging, and APIs.
• Numerical Reasoning — The strongest single predictor of performance in analytical and data-heavy roles.
• Work Style: Conscientiousness — Carefulness, orderliness, and follow-through — the trait most linked to reliability.
