Why this exists

Most interview prep assumes you already know what to study. You don't get told why the answer works, only that it does — and that gap is exactly what falls apart under pressure in a real interview.

This site is the opposite. Every lesson explains the intuition first, then the code. A new problem, explained clearly, every day.

What you'll find here

  • Daily video lessons on Python, LeetCode patterns, SQL and AI — free, no account needed.
  • Written walkthroughs with working code for every video.
  • Mock interviews that adapt to your own resume and target job, with scored feedback across technical, coding, managerial and HR rounds.
  • Study courses and career roadmaps to close the gaps the reports find.
  • Free developer tools — no sign-up, nothing uploaded.

Who's behind it

Hi — I'm the person making the videos and writing the lessons. I build this in the open, publish daily on YouTube, and use the same material I'd want when preparing for my own interviews.

If a lesson helped, or if something is wrong, I'd genuinely like to hear it. The contact page is the fastest way to reach me.

What this site will never do

  • Charge you to watch or read a lesson.
  • Sell your email address or your resume.
  • Pretend an AI score is the same thing as a real hiring decision.
