There were 3 rounds(of which I got rejected after the second round) - Online test, Technical Interview, and HR Interview.
In the online round, they will be evaluating your basic knowledge in digital electronics, OOPs concepts and Logical reasoning.
In the first round of interview(Technical interview), the interviewer will measure your basic knowledge in Digital Electronics, and then on they'll ask about each and every word mentioned in your resume.
The final HR round, as of my colleagues, was kind of a formality.
