Frequently asked
Does it contain model answers?
Yes — but structured as adaptable answer skeletons, not scripts to memorise word for word.
Is this for beginners?
No — it's built for backend engineers who already have at least one real project or production system to discuss.
Is this DSA or system-design theory?
No — the value is in the follow-up questioning around production decisions and failure paths, not algorithms or whiteboard theory.
