Microchip Technology Software Engineer interview experience

I got an introductory call from the manager that lasted about 1 hour 30 minutes, and I wasn’t warned it would be that long. The questions were mostly general digital design topics along with discussions of coding techniques and how I’d handle different real-world solution scenarios. We also covered basic protocol concepts like SPI, UART, and I2C, plus typical strengths and weaknesses.

During the call, the phone even hung up four or five times—something they later said was on the manager’s side, and he apologized. After the interview, I followed up for weeks and never received a clear reply
