Straightforward process. Phone interview with HR to discuss about the role and the background. Then phone screen with the manager. Resume walk through and then SQL questions and one business case. Sql questions were easy. Business case was easy as well but then the interviewer seemed uninterested from the beginning. A business case can have different answers and not necessarily one can you it is right or wrong. The interviewer was expecting the exact answers or phrase what he had in his mind. I did bring up two points which the interviewer mentioned but then it looked like he was not at all interested right from beginning of the call. His comments were so unfair because I gave the exact same answers to the case but phrased it differently. For example: I mentioned that one possible reason for the increase in sale could be sale or discount. His answer was promotion.
