In the first round I had an interview with behavioral questions and then they sent me a haker rank assessment test and it included technical questions regarding linear regression, logistic regression, feature engineering that I needed to describe which feature engineering can be used for the data that they provided, Random forest, and coding in python. It is overall easy and they give you 1 week to solve the problems. Finally, after submitting your answers, you will have a technical interview in which the interviewer will ask you about your solutions to the assessment.
