When They Want to Go Deeper
After system design, interviewers often drill into specific areas. Here's how to handle deep dives:
Common Deep Dive Topics
"Explain how you would implement tool calling"
Strong Answer:
Token Management Questions
"How do you handle context window limits?"
Error Handling Questions
"What happens when an API call fails?"
Debugging Questions
"How do you debug a misbehaving agent?"
- Reproduce: Get the exact input that caused the issue
- Trace: Review the full conversation log and tool calls
- Isolate: Test each component (LLM, tools, memory) separately
- Compare: Check against working examples
- Fix & Verify: Add test case for this scenario
