the last interview (final) was weird. It felt as if they were delibralatty asking irrelevant questions. 1. Assumption of k-means clustering 2. what is logit function, write down the equation. 3) Formula for anova - i mentions test statisic was SSB/SSW - but he wanted theoritical answers. This particular person is a VP in Mumbai, calls himself data scientist but feels like a college professor.
