LeetCode practice builds problem-solving muscles, but interviews are about communicating your thinking in real time and showing that you can adapt when constraints shift. That’s why the same problems that feel trivial alone at your desk can suddenly feel like walls in front of an interviewer. Here are the big gaps you’ve already noticed (and they’re spot on): Thinking out loud: Interviewers want to see your reasoning, not just your final code. Handling changes: They’ll often tweak constraints to test flexibility. Pattern recognition: Spotting whether a problem is, say, sliding window, two-pointer, or DP in disguise. Under-pressure optimization: Interview timing forces you to balance brute force vs. efficient solutions fast. That’s exactly why mock interviews (with peers, mentors, or tools like Leeco AI you mentioned) are so valuable — they recreate the pressure + interaction dynamic that pure grinding doesn’t. suggestions: Don’t stop solving problems, but fr...
