80% of DE Candidates Use AI on Take-Homes. Companies Can't Stop It.

Short summary

80% of data engineering candidates use AI on take-home assignments despite 64% of companies banning it—and 61% pass undetected. The policy is unenforceable at scale; invisible AI overlays defeat detection tools, and 20-hour unpaid assignments make AI use economically rational. Companies like Meta and Canva are pivoting to AI-enabled interviews that evaluate prompt engineering instead of raw coding.

• •Most candidates secretly use AI on technical take-homes, with enforcement impossible
• •Detection tools are defeated by invisible overlays and multi-device techniques
• •Forward-thinking companies are abandoning bans and pivoting to AI-enabled assessments
