In the end, some puzzling questions were asked based on my 6 months internship experience at CDAC. Questions were: 
What type of projects you did at CDAC? What was the problem that your project solved?
Since my project was based on chatbots, I was asked following follow up questions:
-- What are the different chatbots you have used in real-life? Why are they used?
-- What is your opinion about the quality of service chatbots provide?
-- What is the scope of improvements that can be done in the chatbots so as to minimize human efforts involved in query resolution?
