Sparkle

AI-powered interview readiness platform

Diagnose skills. Practice smarter. Get interview ready. A deterministic engine grades every attempt, traces weaknesses through a skill dependency graph, and hands you a personalized roadmap — with an AI mentor that only talks about what you actually need to fix.

Deterministic diagnosis

Grading and mastery scoring are plain, reproducible math across DSA, Python, SQL, and ML — not an LLM guessing at your level.

Skill graph propagation

A NetworkX dependency graph traces weakness upstream and downstream, even to concepts you never answered a question on.

Scope-restricted AI mentor

Groq-powered explanations and mentoring — but only ever about the concepts your diagnosis actually flagged.
