The third round is HR interview round. So HR ask me about my background and what's my long term and short term goals. How this company help me to reach to there. And in next 5 years where I see my self. So this type of questions they ask so you have to be prepared about this kind of questions. And one more thing my HR is books reader so if you mention in your resume that you like to reads books. He definitely ask you about book author and summary of book and what you learn from that book and all this kind of questions. So all the best to you for your interview.
