Perguntas de entrevista da empresa Adstream

After applying I had an initial interview with a recruiter, then I was invited to an on-site interview with the head of Data science. For that one had to prepare an example project of choice to showcase ones DS skills.

The process took around 1 week. After having a discussion with a recruiter, 1st round got scheduled. It was an hour round. I successfully achieved the given task within time, but not sure how the interviewer evaluated my task. the only negative point is, I didn't get proper feedback on why I got rejected because I was very much sure about my code logic.
