About CrackCode

CrackCode is an interview preparation platform built by iodevz.com. We believe that preparing for coding interviews shouldn't feel like a second full-time job.

Our Philosophy

Most interview prep resources dump hundreds of problems on you and say "grind." That approach burns people out before they ever reach their interview. CrackCode takes a different path:

• 15 minutes a day. Each session is designed to fit into a tea break. Short enough to stay consistent, long enough to make real progress.
• Progressive learning. Topics build on each other. Day 2 uses what you learned on Day 1. No random problem sets.
• Visual explanations. Complex algorithms click faster when you can see them in action. Every concept comes with interactive animations inspired by ByteByteGo-style diagrams.
• Consistency over cramming. Small daily wins compound. A developer who preps 15 minutes a day for three months will outperform someone who crams for a weekend.

Who It's For

CrackCode is for software developers preparing for technical interviews — whether you're a new grad getting ready for your first role, or a senior engineer brushing up before switching companies. If you know the basics of programming and want a structured, low-pressure way to sharpen your DSA skills, this is for you.

What We Offer

Our flagship program, DSA Tea Prep, covers 155 days of data structures and algorithms — from two pointers and sliding windows through dynamic programming, graphs, tries, and advanced patterns. Each day includes a focused lesson, visual animations, and a linked LeetCode problem for hands-on practice.

More programs — including System Design and Behavioral Prep — are on the way.
