I was under the impression it would be a 30 mins with HR since it was only 30 mins long and the very first interview. Instead it was the MD and after 30 mins I was asked if have more time. The MD was very nice and asked two algorithmic questions.

First Interview was with the Hiring Manager. He asked me about my experiences and follow up technical questions on my Machine Learning projects, eg. How is the machine, learning ? . He also asked Linear Algebra questions.
