I was a B.Tech student at the time and I was contacted over Quora by a senior person in the division. I interviewed for an Intern position and listed Machine Learning and NLP as strengths. Two telephonic interviews. Questions asked were related to my projects in college, my papers, the research that I am doing now. In the second interview, questions related to programming were asked in my preferred language. Also, questions included different paradigms etc, normal technical interview stuff.
