Received invitation of first round interview within 5 days. 45 minute Interview revolved around past projects, motivation towards Data Science and many conceptual data science questions.
Received an invitation for the final round of interviews (i.e. Superday) which had three 45 minute interviews back to back:
1) Business Problem Formulation: sounds like a case study interview, but mostly behavioral with case related questions here and there.
2) Modelling and Algorithm Knowledge interview: Questions about core concepts of Machine Learning and how to use it in production environments. Knowledge of EDA related algorithms is important too.
3) Programming and Data Manipulation: SQL, Python, EDA, ETL stuff. Some behavioral questions too.
They took a long time after that but eventually rejected me.
