Dev, you can go for Data Science, at Christ University, Pune. Data Science is a vast field with wide range of opportunities laying ahead for you.

But, I must mention, placements in data science is not much available immediately after Btech, either you have to go on studying and research in that field by numerous good courses offered, or you can straight forward complete your Masters in data science. Companies usually hire data scientists who are Mtech or Phd holders.

I wish you good luck!
