There was one round of technical interview. Questions were asked based on the role, mostly about C / C++ and storage and memory. Aptitude questions were mentioned in a paper and asked to solve. Projects had to explained.

I applied through on campus. The interview was around 5 rounds. First is the written test. Next 2 rounds will be online mode of interviews focusing on the basic concepts of Microcontrollers (AVR AT Mega or 8051) and digital electronics. They focused on C programming coding part as well as the theory part. Then if you have cleared the 2 online interviews, they will call you to the off campus interview at Chennai. In off -campus interview, they will again start from the written test. Here, written test will be fully coding part of C programming. They will give 4 coding questions printed on a paper and ask you to write code directly on A4 sheet provided. Then again a technical discussion with same interviewers who took in online, After that if you clear that round we have manager round and in manager round, mostly he focuses on general topics like hobbies and some technical discussion what mentioned in resume and some core fundamentals of ECE.
