Since my projects were based on Machine Learning and Android development i was asked similar questions. In the tech round, I was asked to implement a REST API for retrieving a contact database and sending it across devices. It was followed by explanation of my ML project based on feature extractoin, SVM and KNN. Then he gave me a coding question which was similar to a question named "Overlapping Intervals" in geeksforgeeks.org There were other basic questions regarding the kind of development work i prefer to do and life goals etc.
