Memorizing without understanding. Reciting definitions without reasoning is obvious to interviewers. Understand the why behind each concept; reasoning, not memorization, is what they actually test.
Because if a project is on your resume, interviewers expect you to walk through architecture, choices, a hard bug, and what you would improve. If you cannot, it suggests you did not build it as deeply as you claim, which breaks trust.
Because a feature that only handles success is not production-ready, and interviewers notice. Describing loading, error, and empty states when you explain a feature shows you understand real-world engineering, not just happy paths.
