3 rounds of interview 1) technical 2)manager 3)HR overall average interview process and resume based question. question asked on CAN , DCM , Microcontroller , CAN protocol and cprogramming questions

I applied through Campus. there were 4 rounds in total. 1. Aptitude : had verbal, quants, technical. Was quite simple. Concentrate more on Microprocessor and controller and digital systems for technical. Quants had a lot of ratio proportion and probability and other topics as well. 2. Coding : Patterns like Christmas tree, a 5 pointed star and a house were asked to print using "*" in C or any other language. 3. Technical : Actually it depends on luck as everybody gets asked different questions. I was asked about logic gates, diodes, ADC DAC, registers, mpmc, etc. Questions about mini projects and inplant trainings and internships would be asked. 4. HR round : 90% if you make it to the HR round, you're placed. They just ask about yourself and abut your family and other basic stuff.
