The technical interviewer asked me literally everything from regression, classification, PCA, sentiment analysis to deep learning, Design of Experiments and Big Data technologies etc. I know it sounds stupid, it is impossible to have hands on production environment experience on all these technologies unless you are in teaching field that too only on sample data sets. May be there are some 100 professionals in the whole world who got scope in corporate sector to work on all these techniques to solve real business problems. The interviewer also asked many scenario based questions, specifically potential challenges a group like Domino's in India could have and how I would approach addressing those questions.
