What is the best answer I could give to HR (HR round) if asked, “Why are my grades low in B.Tech.?”?

If you are willing to speak the truth, be ready to answer the follow up questions too. For example: If you say that you became addicted to drugs, the next question they may ask is are you still addicted?

I know a guy who was asked the same question in an IIM interview and his answer was “I became addicted to drugs!” And surprisingly,he was able to convert.

However, if you are willing to speak the truth, be ready to answer the follow up questions too. For example: If you say that you became addicted to drugs, the next question they may ask is are you still addicted? This may be followed by - What did you do to overcome that? How should we trust you that you don’t become addicted again? There are other candidates who have high CGPA. Why should we select you?

The advantage that you will get by speaking truth is that you will not have to frame a lot of stories. And trust me, when it comes to these type of questions, interviewers love to grill the candidates. They will catch your lie one way or the another.

Moreover, this would show that you are honest. And interviewers yearn for honest candidates usually. So, this might work in favour of you.
