I went through two Interview steps. The first one covered the machine learning fundamentals and the second part went through algorithm design. The machine learning part was interesting and efficient and was moderate level. The algorithm design part on the other hand was not organized. The interviewer asked me to think loud but kept interrupting and somehow misguiding me. I think the problem was that I was coding in Python while the interviewer seemed to come from a C++ background. So, he did not really get what I meant by some data structures, etc.
