Frequently asked questions
Is maang.io free?
Coding Interview 101 is completely free. Advanced tracks and levels are rolling out — reserve early access to lock in the launch discount.
How do I sign in?
Sign in with your Microsoft account (Google coming soon). We never store a password — authentication is handled by your identity provider.
What makes maang.io different from LeetCode?
Instead of grinding a long list of problems, we teach the underlying pattern from brute force to optimal, with hand-drawn diagrams — so you can recognize and solve whole classes of interview problems.
Do you track my progress?
If you're signed in, yes — so your learning is saved across sessions. See our Privacy Policy for details.
Are you taking payments yet?
Not yet. Coding 101 is free and reserving early access does not charge you. Paid plans and checkout are coming soon — see Refund Policy.
