Data scientist is a rare breed and a well celebrated one. Middle of this year, we took it upon us to identify the top data scientists in the country. The initiative was asked for by many of our avid readers.\nI personally believed that, given our inroads in the analytics ecosystem of the country, this initiative would essentially be an easier take.
