I got interviewed by a manager and a developer. The interview was a strange and frankly unpleasant experience. Both interviewers were unresponsive, emotionless and cold, strongly giving the impression that they really didn't want to be here. I faced my fair share of rejections in my internship search, but this complete lack of basic soft skills and enthusiasm made this the only company where I was actually glad to have gotten rejected. A week before I was selected for an interview, I was contacted and sent a link to a 3 hour long test. The first component of the test contained multiple choice and true/false questions related to python's machine learning libraries (pandas, numpy, matplotlib, scikit). The second component involved building a simple decision tree model in python using the data provided.

It was only 1 interview with 3 people. It included behavioural questions, and technical questions. The interviewers were really friendly and welcoming. The questions level was very reasonable and they care more about how you analyze any problems and provide some initial sensible solutions.
