GoDataDriven Machine Learning Engineer interview questions

I was denied entrance to application procedure after talk with HR. She thought my technical background was lacking, eventhough I completed a MSc in Maths. The interviewer was nice, but I didn't agree with her reasoning. At GoDataDriven they really want you to have presentable technical GitHub stuff, otherwise they won't let you continue.

Typical interview process. First, a very nice and friendly interview with a recruiter gave me the impression that GoDataDriven would be a great company to work for. The second interview was a technical one, questions weren't difficult. But the interviewers that they think they are better than everybody.
