The gap between reading an interview round and being ready for one is a single evening of practice. **Turn each question into a task** For every question in a write-up, write down the pattern it belongs to — sliding window, two pointers, heap, graph traversal. If you cannot name the pattern, that is the gap, not the question. **Then answer three things** - What would I have said out loud in the first two minutes? - Which edge case would have broken that answer? - What is the complexity, and can I say it without hand-waving? Two rounds a week, done this way, covers more ground than a hundred posts skimmed.
