IPSY Machine Learning Engineer interview questions

The first round was a simple coding round with questions related to regularization, performance measures and easy level coding questions. The second round was disappointing for me as the interviewer asked me if I am interested in creating Machine Learning Models or in Testing/Deploying it. I said I am interested in the Machine Learning and then he said that I should apply for Data Science position as this position is not for me. So, I asked him that I am also interested in Testing/Deploying and he have me a coding challenge to solve which included defining functions to find Mean, Median and Mode. It was really disappointing.

I applied online and received a hacker rank coding challenge. After taking the challenge, I got rejection email saying skillset is not an exact fit. I think that because I didn't get the 100% correct since I remember I can't make my code pass all test cases in the last question.
