Hey,

• For personal interview,  prepare for basic questions that are normally asked like "tell me about yourself, where do you see yourself in 5 years, why do you want to do MBA",etc.
• It's totally okay to say 'I don't know' in personal interview rather than saying something stupid or something that won't make sense.
• Watch YouTube videos to learn how to answer such questions, what the interviewer wants to listen and what should not be the answer. One of the good channels for such videos is 'The urban fighter'.
• For GD, stay updated with the current affairs.
• Read newspapers daily and watch news.

Some tips for GD:

• Do not start a debate. Remember, it's a discussion. So keep calm and answer.
• Don't repeat the same point again and again. And to avoid this, keep your answer short so that you have something to speak again.
• You are not there to prove anyone wrong. They just want to know about your opinion and communication skills.
• Be confident and clear when you speak. Don't start first if you don't have the idea about the topic. Hear others and find ideas.
