Abhay - the guys in this thread have provided excellent responses on where to find information to quickly get started with Qlik Sense. Hopefully it is not overwhelming, but should be very comprehensive and get you started on your own.
I present a weekly webinar series, Getting Started with Qlik Sense on Thursdays at 2 PM EST - where I cover an introduction and basics to usage and development with the product. You can register here:
