I received a message on LinkedIn from a recruiter regarding a position I had applied to. He mentioned that this position requires a Ph.D. in Machine Learning, and I am an M.S. graduate with a specialization in Data Science and Intelligent Systems. So, I explained how I could be a best fit and possess the required skills for the job, and he was convinced.

The technical interview was scheduled for an hour, and the interviewer seemed okay while discussing the team and job responsibilities. Then, we moved to the coding part, where I was asked to implement an ML algorithm. My implementation was good.

The bad part comes here: the interviewer was silent throughout the entire coding session and didn't seem interested in the code at all. He didn't ask any questions related to my implementation. Three days later, I received an email stating that we are not moving forward with my application.

What am I supposed to learn from this interview?
