Took 2 months to get back after application. Sent a data science challenge on hackerrank.
Given a dataset which we cannot even see properly on hackerrank, build 2 ML models and answer insight related questions within 2 hours. It made no sense. The dataset was in raw form (transaction level data), had to be studied and converted into features and target, split for training/testing and report accuracy. This is not how a data science task can be completed.
