To make matters worse, the interviewer asked me to implement self-attention mechanism from scratch (the only question he asked), which is a task that even experienced engineers would find challenging. I don't have any experience in NLP by the way. I was stunned by the request, as it was completely unreasonable and unrealistic for an interview. He straight away told me "I am not interested in candidates like you" and ended the interview in a rude and unprofessional way. The interviewer showed no interest in my background or experience, and seemed more interested in showing off their own knowledge and intelligence. It was a power trip, plain and simple. I left the interview feeling completely demoralized and disrespected. It's a shame that a company would allow someone like this to represent them in the hiring process. I wouldn't wish this experience on anyone and would strongly caution anyone considering interviewing with this company to proceed with caution.

code questions: listL=[[1,2, 3],[4, 5],[6 ,7 ,8 ,9 ,10]] expected output: 6 9 40 follow up to print sum columns. I explained my approach to it.
