I was shortlisted from the college.Interview was held at their company.In college 3 rounds.written test,2 rounds of technical interview. After 1 month interview at their company.there were 3 round again. Interview question are related to control system,signals and system,micro controller,microprocessor,C related questions

Technical(n number of rounds) + HR. Technical round never ends. Its a long questions with a panel of min three people firing questions at you. Control system is a main area of focus. But the number of rounds is very uncertain, It never ends in that terms. Very rude panel usually.
