Avanade Data Visualization Engineer interview questions

I was contacted by a recruiter and decided to try out for the said position. I talked with someone from HR via phone call for the first round and the person told me that I'd be talking to a technical interviewer in the second round. Upon the second round of call, I think I was not expecting of what would the interview process be. I got asked several questions (~20 questions) - it was like a test session but conducted verbally.
