面试指南

• For algorithm questions: structure your answer by stating the problem, the approach you took, the trade-offs considered, and the final outcome with metrics.
• For debugging questions: describe your systematic process – reproduce the issue, isolate the component, analyze logs/traces, test hypotheses, and verify fix.
• For experience questions: use STAR method (Situation, Task, Action, Result) to provide concrete examples with quantifiable impact.
• Describe your experience with auto exposure control algorithms. How do you handle challenging lighting conditions?
• Explain how you would debug a focus hunting issue in a camera system.
• How do you ensure algorithm performance across different sensor and lens combinations?
• Can you walk us through a project where you optimized a 3A algorithm for an embedded system?
• Describe your experience with C++ in embedded Linux environments. How do you manage memory and performance constraints?
