Avoiding LLM Hallucinations in Interview Prep
Avoiding LLM hallucinations in prep means ensuring the AI-generated answers you study—code, designs, or facts—are verified and factual, not fabricated or misleading.
When to Use
Use LLMs for brainstorming solutions, summarizing complex topics, or generating mock questions—but always cross-check outputs with documentation, test runs, or reputable sources.
Example
If ChatGPT gives you a “working” function using a non-existent library, running the code will instantly reveal the hallucination.

Why Is It Important
Depending on hallucinated answers can break your confidence in interviews or lead to wrong solutions. Verification ensures what you learn is technically sound and aligns with real-world standards.
Interview Tips
If asked about LLMs, explain how you verify AI outputs—running tests, checking against design best practices, or comparing answers to official docs. This shows technical maturity and responsibility.
Trade-offs
LLMs save time and expand creativity but may produce inaccurate details. Balancing speed with verification is key to getting the best of both worlds.
Pitfalls
Blindly trusting AI-generated explanations or designs without validation. Always question code snippets, database schemas, or architectural patterns—especially in critical prep areas like Grokking the System Design Interview and Grokking Database Fundamentals for Tech Interviews.
