How do I convert a call from tapmi?

To get into TAPMI, clear the GD session, and perform well in PI. Your marks and CAT score should also be good. Last year my brother applied here. Let me share his experience, which might give you a clear idea.

• GD topics are mainly taken from current affairs. They might also provide debatable topics, to evaluate the discussion. My brother was given the topic “Should Burqas be Banned During Exams?”. Out of 12 people in the group, 4 were selected for the PI round.
• In PI, various types of questions were asked. This included from - “Describing Yourself” to “Where do you see yourself in 5 years”. Mention your family background briefly, but mostly concentrate on yourself, your accomplishments, your skills, and your strengths. 
• They also asked about - Why he chose MBA and why in TAPMI. Also why he did not opt for a job but for an MBA. Confidently and answer with honesty, this will definitely create a good impression.
• After that, you also might be asked about current affairs and your extra-curricular activities. How they benefited you and what role does it play in your career, are some of the things you should be prepared to answer.

Overall, even if you don't have an answer, be confident and speak clearly. If you don't want to bluff your way through an answer, tell them confidently that you don't know.
