phone interview, data challenges, onsite. Overall positive experience for all the technical rounds. Most interviewers are trying to understand what you know and how much you know rather than asking you something you are not familiar with. For example, I was asked an NLP question in one round of interview. I mentioned that I not very familiar with NLP but I will try to answer based on my general knowledge in NLP. The interviewer immediately decided to switch to questions in other fields "Let's talk about something you know". And then we had a great conversation about several algorithms/techniques/design.

My interview started with a stats coding round where I was asked to code for expected value for a problem and the second interview was a case study which was quite easy
