Questions

What exactly do I get?
A zip with three files: the playbook PDF (65 pages), the same content as a markdown file (paste into Claude/ChatGPT), and the interviewer prompt file that turns them into a mock interviewer.
Why ₹99?
Because it was built from other engineers' real interview experiences, and this price lets us split the earnings with everyone who contributed while keeping it accessible to students and junior devs.
How is the money split?
Contributors get a share proportional to what they submitted (questions, follow-ups, framework write-ups). Reach out if you want to contribute to the next edition.
How do I pay?
UPI, cards, or netbanking through Razorpay's secure checkout. No account needed.
