SharpSkill – I built a Freemium tool with Cheatsheet to crush tech itw
Tech-specific cheatsheets and simulators fighting for attention against LeetCode and Pramp.

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.

Tech-specific cheatsheets and simulators fighting for attention against LeetCode and Pramp.
Stack-specific guided interview flows, timed validation tests and recruiter-facing shortlisting make this feel like a staged rehearsal rather than a bag of LeetCode problems. The inclusion of flashcards and per-tech progress tracking is practical, but the space is crowded—I'd need to see evidence (question sourcing, scoring transparency, placement stats) to call this a real differentiator.
Stack-specific drills are smart, but LeetCode's network effect is unbeatable.
Yet another interview prep site competing directly with LeetCode and Pramp.
Landing copy and features are focused: real interview questions, flashcards, timed validation tests and progress tracking plus recruiter analytics — that two-sided approach is sensible. The page looks sharp and communicates product flow, but there’s little on the site showing what the ‘AI’ actually does or sample outputs; prove the personalization/scoring and this moves from familiar competitor to a must-try.
Interview prep for 10+ stacks, but LeetCode already dominates this space.
