First round was an offline assignment. Post that, called for a face-to-face interview where I was interviewed on Python Language, Machine Learning and what is on my profile. I was not offered because I had senior level knowledge in "data-science python" and they wanted senior level knowledge in "python language" according to the HR, which doesn't make sense :) Python is a general-purpose language and can be used for a variety of applications. A person who is working in it for 3 years can quickly grab the syntaxes and concepts of a different application of the language. Good luck to the team :)
