It was first an online test of about 30 technical interview questions and also a combination of aptitude questions, after that main interview will be of full technical based on your technical knowledge and after that HR round would be there, this is the whole process.

My area or branch is electronics and communication engineering, but most of the questions are from the electrical engineering branch only, so it depends on your interviewer.

If u have luck, u will get placed; otherwise, you will not.
