EMI/EMC
EMI/EMC (Electromagnetic Interference/Electromagnetic Compatibility) is a critical aspect of electronic product design and manufacturing. In simple terms, it's about making sure electronic devices work properly without interfering with other devices and can function correctly when exposed to electronic disturbances. Think of it like making sure your microwave doesn't disrupt your Wi-Fi signal, or your cell phone doesn't cause static on nearby speakers. Professionals in this field help companies ensure their products meet safety regulations and work reliably in real-world conditions.

Example Interview Questions
Senior Level Questions
Q: How would you approach EMC issues in a new product design?
Expected Answer: A senior engineer should discuss preventive measures during design phase, mention cost-effective solutions, and explain how they would lead a team through compliance testing and troubleshooting.
Q: What experience do you have with international EMC standards?
Expected Answer: Should demonstrate knowledge of different regional requirements (FCC, CE, etc.), explain how to plan testing programs, and discuss experience managing compliance projects across multiple markets.
Mid Level Questions
Q: What methods do you use to identify EMI sources in a product?
Expected Answer: Should explain basic troubleshooting approaches, mention common test equipment usage, and demonstrate understanding of typical interference sources and solutions.
