Ans: Hey, first of all congratulations on clearing so many rounds and reaching the personal interview round!!

Now regarding the preparations...

1. Be impeccably dressed for the interview, this shows you care. Also you need to appear professional and confident
2. Enter the interview room with confidence
3. Enjoy the whole process of being interviewed, it's about you, that's why it is called the personal interview
4. Prepare the questions that are relevant to your role and the company you will be working for. Know a little about the company's competitors
5. Prepare for the usual questions, tell us a little about yourself or introduce yourself, what are your strengths and weaknesses, why should we select you, etc .... these questions are for you to showcase the real you...in a positive light. This is where you show your authenticity
6. Prepare for the Q and A with someone asking you the questions and you replying

Have the confidence, you have come so far, I am sure you'll clear this round too!!

All the very best!
