Nervous about your upcoming technical interviews? Stop stressing and start swiping. SwipePrep takes industry-standard coding interview questions and turns them into a fast-paced, flashcard-based swiping game. How it works: Read through a classic interview question (like Two Sum or Reverse Linked List). Review the core intuition, optimal time/space complexity, and solution code. If you know it perfectly, swipe right to mark it "Mastered." If you struggle, swipe left to send it to your "Revisit" stack so the app can test you on it again later! Why you'll love it: Study Anywhere: Review complex Graph Theory and Dynamic Programming patterns while on the go. Visual Progress: Watch your "Algorithmic Rank" climb. Our dashboard includes a dynamic radar chart showing your mastery across Arrays, Strings, Trees, and more. Activity Heatmap: Keep your daily streak alive and fill out your 30-day activity grid. Curated Content: We focus exclusively on the high-yield patterns that actually get asked at top tech companies. Stop grinding endlessly and start studying efficiently.
