Inside Big Tech: how the apps you use every day actually work.
Short, story-driven lessons that open with a real product moment — booking a seat on BookMyShow, matching an Uber, streaming an IPL match — then reveal the engineering idea behind it, the way a great senior would explain it.
Interviews increasingly test how you think, not just what you memorised. Engineering Thinking builds that muscle with 31 lessons drawn from apps every Indian student uses — Swiggy, Zomato, Flipkart, WhatsApp, UPI, Zepto, Instagram, JioHotstar, ChatGPT — each one unpacking a real system-design or DSA idea.
Every lesson makes you predict the answer first, tells the story, then hits you with the real interview question that concept unlocks and a 'can you solve this?' challenge — so the idea sticks and you can talk about it under pressure.
How it works
Predict first
A think-first question before the story primes your brain — you learn far more when you commit to a guess.
Read the real story
The concept is explained through a real product moment, not a dry textbook definition.
Meet the interview question
Each lesson reveals the actual interview question that concept powers, with a model answer.
Can you solve this?
A mini challenge cements it, so you don't just recognise the idea — you can apply it.
