The whole interview process was poorly organised. There were 2 interviewees. In Data Science area, they were not clear which specific area the role should work in. They started asking questions right from machine learning projects to machine learning technical questions to deep learning to natural language processing. They needed someone to know everything of data science. In Data Science, we specialise in one of the fields and I told them my area of interest is Deep Learning. I answered all Deep Learning questions correctly, but they humiliated me saying shall we ask some more or should we finish the interview. You should never make such people take interviews who harass during the interview process.
