NASSCOM recently held a NASSCOM Product Conclave (NPC) in Kolkata and organised a special section for the students, titled eSummit. There were 2 competitions under this banner – a business plan competition and an idea to prototype. I was called upon to mentor the applicants in making effective presentations and we had a 1 hour long webinar which was very well attended and judging by the number of questions, people found it quite useful.
I have provided the template Powerpoint presentation here. You will find it a handy reference if you are going to present to some jury or investors.
