Technical round questions are mostly around the basics of rectifier circuits, embedded systems (MSP430 and PIC18F), communication protocols (UART,I2C and SPI)and little bit of MOSFET and IGBT questions. They might also ask you about the projects you've done and any previous internship experience. The HR round revolved around situation based questions and about goals, where you see yourself in 5 yrs etc. The questions also might be a little towards ethics and company culture fit.
