How to Prepare
- ✓Brush up on KVL/KCL, Thevenin/Norton equivalents, and op-amp configurations — foundational circuit questions are common at all levels.
- ✓Be prepared for whiteboard circuit design: bring pencil-and-paper reasoning, not just simulation results.
- ✓Know the tools in your stack (Altium, KiCad, Cadence Allegro, SPICE) and be ready to discuss design decisions you made with them.
- ✓Prepare a real hardware debug story — oscilloscope captures, root cause identification, and design revision.
- ✓For power electronics roles, know switching converter topologies (buck, boost, flyback) and their trade-offs.
