My word of Advice
1. Do Not Fake
2. Presentation skills matters the most
3. Do not try to study everything I was asked. Maximum things was part of my interests
4. Fail safe. If you do not know anything. Explain Something and then try to deviate attention towards your part of interest.
5. Practice Correct words to be spoken
6. Go with a fresh mind. They would be generating questions on the statements you make.
7. Try to bring interviewer to your interests.
8. Revise all your skills one day earlier
9. Go through your Resume one day earlier
10. Don’t panic if you give wrong answer or if you don’t know. Its absolutely fine to fail. Yes, it is OK if you fail. You would be judged relatively.
