They asked to solve a use casein own laptop before appearing for the interview, and it would be evaluated as the very 1st round. HR would timely follow up for the same too. However, after I reached the venue with the solution the interviewer did not bother to look at it, and asked five questions only from DS algo. I requested him to discuss about some technical staff from my previous work exp, and then he quoted"In no good compnany you will be judged based on your previous work or experience. "(Such a funny crap I got to hear for the first time in my life.. rofl). It was just a waste of time. No learning experience and they should not have asked to solve the use case by wasting the time of a professional if it is not seen at all. However, the attitude of HR persons were very friendly and professional.
