The first round was an online assessment in which they asked basic ECE topics related question(solving ckt for Req, wheat stine bridge, and some transistor related questions). The second round was a GD , where they gave us a topic. Our group was of 8 members, each one of us put our respective views and based upon that they selected 3-4 members per group. The third round was technical interview, where the panel asked me about my Btech project in detail(it was on solar cell designing). Then they asked about embedded C and how the code executes. They also asked some detailed questions about Arduino , like what kind of cpu is used and how it works. Further they asked me to design a car system, on how it will get parked in a parking lot. They also gave one situation which i had to code on a paper in a language of my preference(I chose C++), and they asked me to optimize the logic.

First round is online test, second round is GD, third round is HR interview the interview consist of aptitude which is medium level. The GD consists of topics related to current scenario. HR was friendly.
