SharpSkill – I Gamified a LeetCode-like tool to crush Tech Interviews

SharpSkill pairs timed, mission-oriented validation tests and flashcards with per-technology progress tracking and recruiter-facing scoring — so candidates train under interview-like constraints while employers get a shortlist based on client-oriented metrics. The homepage communicates feature-focused thinking (real recent interview questions, position-specific tracks, validation tests) and the UX feels intentional, but this is a very crowded space and I didn’t see an obvious technical or pedagogical differentiator that would make me switch from existing tools.
