Hr assigned a Machine Learning Task. Followed by 2 technical rounds about Data Structures and algorithms. Basic machine learning question about the task. 1 Round with manager. I wish the manager should be a bit more experienced. Rejected based on np.vectorize and Dask packages. No ML questions were asked during the process in the managerial round. Please prepare np.zeros, np.ones and brush a week on libraries and optimization than data science as the manager is only familiar with that stuff. Don't worry about ML.
