The algorithm interview has never been isolated and validated in the peer-reviewed record — not once. Here is what the research hierarchy actually shows, why AI finished off whatever was left, and what work-sample assessment replaces it with. https://www.codepraxis.co/blog/why-algorithm-interviews-fail https://www.codepraxis.co/blog/why-algorithm-interviews-fail Sun, 05 Apr 2026 09:00:00 GMT Hiring Google's own research found essentially zero correlation between algorithm interview scores and on-the-job performance. Work-sample tests outperform every other hiring method. So why is the industry still clinging to LeetCode? We dig into the data, the hidden costs, and the alternative that actually predicts engineering success. https://www.codepraxis.co/blog/ai-in-technical-assessments https://www.codepraxis.co/blog/ai-in-technical-assessments Sat, 28 Mar 2026 09:00:00 GMT AI & Integrity 89% of engineers use AI tools daily. Assessment scores have inflated 34% while job performance stayed flat. Banning AI is unenforceable. Ignoring it is negligent. We make the case for the harder third option: designing assessments where AI usage itself becomes a signal of engineering judgment. https://www.codepraxis.co/blog/real-world-coding-challenges https://www.codepraxis.co/blog/real-world-coding-challenges Sun, 15 Mar 2026 09:00:00 GMT Product Every platform claims their assessments are realistic. Almost none deliver. We introduce a five-dimension fidelity framework for evaluating assessment quality—environment, codebase, task, tools, and evaluation—and show why fidelity matters more than difficulty.
