Trendwise Analytics interview questions

They asked everything I mentioned in my resume. I explained whole my capstone project I did in my final year MBA. He asked some questions inbetween my explanation I explained it.only 1st round is completed. Next 2 rounds is yet to complete.

I applied online through their website and the process took 1 day. There was no interview. The company asked whether I'm willing to work without a pay. They sent me the offer letter upon accepting the condition. I accepted the offer but didn't go.
