Mock Interview Workflow
Practice the full loop: understand, choose a pattern, explain clearly, code, then test.
- •Did I restate the problem clearly before solving it?
- •Can I explain why the chosen pattern fits?
- •Did I leave time to test edge cases out loud?
Mock interviews are not only about getting the answer. They are about making your thinking visible. A strong interview answer usually sounds like this: clarify the problem, say the pattern, explain the tradeoff, code the idea, then test it. Good communication makes the logic easier to trust.
In interviews, invisible thinking is almost as risky as wrong thinking.
- 1Restate the problem in plain words.
- 2Call out the likely pattern and why it fits.
- 3Outline the algorithm before coding.
- 4Code the clean version, then test edge cases out loud.
Going silent and coding immediately makes it hard for the interviewer to follow your judgment, even if the final code is decent.
Design Add and Search Words Data Structure
Use a Trie for addWord. For search, DFS recursively and treat '.' as a wildcard that tries every child node.
Word Search II
Build a Trie from the word list. DFS the board while traversing the Trie simultaneously so invalid word paths are pruned early.
