NEC came into our campus. 1 round was a coding round, the questions asked were easy to moderate level followed by 2 Technical Interviews. In both interviews, they asked about core subject topics and 2 or 3 coding questions. Finally, after the technical interview, there was an HR round which was telephonic and normal questions were asked like, Why do you want to join NEC? , Why do you think you are a team leader? etc.

interview level was between medium to difficult (for some students interviewer asked easy level question) . But in my case interview was mostly of difficult level and i was asked about my advance level concepts of react and machine learning.
