I was at the Smart India hackathon when I was approached with this opportunity randomly when I was working on some project at the hackathon which was held in Coimbatore/Bangalore.
Show up at hackathons and people will take notice. I did not apply for this. I was selected based on the initial conversation I had with the representative from the company who was sent to the hackathon to find some candidates for internships.
Video interview. I was asked general questions and nothing too technical.
I used to read newspapers a lot and that made a good first impression. So... read newspapers. Use the inshorts app to read news in your free time. I still recommend the newspaper though.
Communication skill matters. Speak without getting nervous. As someone who was diagnosed with Childhood-onset fluency disorder, I managed to speak without stuttering. If I can, you can too.
