About the Clean code test
As an engineer, the last thing you want to refactor is spaghetti code. It’s time-consuming, wastes client funds, and is often one of the worst parts of writing code. This hiring test evaluates conceptual understanding of clean code principles through real-world scenario-based questions.
This hiring test uses language-agnostic questions to measure an engineer’s ability to write code that follows the SOLID, DRY, and YAGNI principles, and this screening test has a strong focus on “clean code,” as described by prolific computer scientist Robert C. Martin.
The test will also focus on implementation strategies, such as when to use an interface versus an abstract class and how to properly scope classes, properties, and more. High-quality code depends on high-quality documentation, comments, and naming conventions, and this hiring test includes questions on these important software development topics.
Wouldn’t it be nice to simply work on code that comments itself, lends itself to swapping out the old driver for a service for the new one, and just makes your life so easy that it rejuvenates your love for writing code? Use this test to recruit and hire developers skilled at clean code concepts! This screening test evaluates developers at an intermediate level (i.e., about two years experience).
