Who it's for
- Engineering managers
- Operators replacing weak assessments
- Founders building hiring processes
- Hiring managers reducing false positives
Coding tests evaluate programming ability through timed challenges; skill demonstrations evaluate ability through real or recorded work samples. Both measure capability — but they predict different things, and one is often the wrong tool.
Coding tests predict abstract problem-solving in a controlled environment. Skill demonstrations predict craft and real-world performance. For software engineering, both have a place; for service, trades, and craft work, demonstrations win every time.
Short answer
Coding tests (Codility, HackerRank, CodeSignal): predict algorithmic skill.
Live pair programming: predicts collaboration and reasoning under pressure.
Take-home projects: predict realistic work output but cost candidate time.
Skill videos: predict craft, presence, and customer-facing ability.
Pick by what predicts performance in the actual role.
Comparison
Coding tests (Codility, HackerRank)
Best for: software engineers, algorithmic skill
Live pair programming
Best for: senior engineering hires, real-time collaboration
Take-home project
Best for: design, full-stack, product work; costs candidate hours
Verified skill video (Vetano)
Best for: service, craft, presence, customer-facing roles
Examples
Codility for screen, system design conversation for final — measures the actual job.
Brief technical test + verified skill video showing on-site communication.
Skill video alone — the demonstration IS the work.
FAQ
For algorithmic and screening purposes, yes — but research shows moderate correlation. Pair with system design or pair programming for senior roles.
Only if they're under 3 hours, paid, or directly relevant. Long unpaid projects shrink your candidate pool fast.
Skill demonstrations — short videos, work samples, or trial shifts that show the actual work.
Different tools. Codility tests algorithmic skill; HireVue does structured async video interviews. Pick based on what you need to see.
For technical roles, no — algorithmic ability is best measured directly. For service roles, video is the better signal in the first place.
