BlackPepper Technologies Machine Learning Engineer interview questions

Telephonic round. The interview was with one of their VP who did not know much in ML/DL. So he did not ask much technical. I am still wondering what went wrong. To the management, if you are not interested in candidates then please don't waste their time and effort. First, you decide if you want to hire or not then decide what are you looking for and then call/interview someone. It would be better if someone who has really worked in the domain, is the interviewer.
