I proposed an idea to speak at Big Data Conference in Hyderabad. This was a local event. The event gave me a free ticket. The event did not pay for my travel and accommodation. My employer did not pay my travel expenses, and I was working while speaking at the event. It took me 2 weeks to prepare for my 45 minutes speaking slot, and I had a mostly good time. I'm a man who has been speaking for 1 year. This was a for profit event.
