L1 : Technical questions about Python, Machine learning. They themselves don't have any knowledge about above technologies, so ramble about technical terms. Even if you just memorize definitions and concepts of Machine learning like what is bias/variance, what is supervised/unsupervised etc from any websites you are good to go. They won't take coding test on python ( they themselves don't have any expertise in it, so don't worry you would do just fine.) For SQL just practice some easy LeetCode questions focusing on group by, order by, having clauses. They ask to write queries on notepad just to check your approach and logic. L2 : Will be with your Reporting manager. Expect traditional questions like 'what you do in your free time', 'your hobbies', 'where do you see yourself in x years'. This interview won't take much than 15 minutes.
