I’m a Former CTO. Here Is the 15 Sec Coding Test I Used to Instantly Filter Out 50% of Unqualified Applicants.
Former CTO Jose Zarazua shares a simple coding test to filter out unqualified applicants in recruitment. The test involves a code snippet that many will answer incorrectly if they copy-paste rather than think through, allowing a quick assessment of programming skills. This method helped identify 50% of candidates using AI/Interpreter answers and revealed that only 3% answered incorrectly, effectively streamlining the hiring process.
