I was contacted by a technical recruiter followed by an amazing conversation on phone about my technical interests and experience which led to a phone screen. The phone screen was interesting, it started off with a behavioural phase where I had to explain a little bit about myself and an interesting project I did. The interviewer was clearly not happy with the project I described. This was followed by a series of Machine Learning questions like what technologies (classification,etc) have you worked on etc and what algorithms did I use before. Next was about overfitting, how do I identify and overcome it, the interviewer was unhappy with the usual bias vs variance,cross validation, re-sampling,feature engineering,regularization, other methods(ensemble etc) based answers and had no intention of giving a hit of what was being expected and there were some routine machine learning questions that test if I had other basic ML knowledge. This was followed by a coding challenge on codepair. It was an easy problem straight from leetcode (string + dp) but the funny part was the interviewer was pissed off at the dp solution and demanded a 2**n recursive solution. At this point it was clear for me that interview derailed a long time back and felt like the interviewer was not at all interested in making the call. The obvious reject came a week later on a holiday in the usual email format. PS: The interviewer constantly yelled whenever he did not like my answer and made some unprofessional remarks about how people lack experience in dealing with problems.
