one HR call, Next 2 rounds with Technical Team members , 30 mins each . They asked regular questions on regression and model building framework. Next was onsite with Hiring Manager, Senior Manager and 3 other team members for about 1-1.5 hours. the experience was good and they help you lead the answer and fill up the blanks helping you through the interview.
Take home exam on data analysis and statistical inference, and then two rounds technical interviews, mostly probability and classical statistics and machine learning. Some simple algorithm questions done verbally too.
First round was panel Interview with 2 people, Ask questions on Statistics and resume. One was the VP of the team and other was regional manager. The Interview was not that difficult. But then I was ghosted. There was no reply from either HR or anyone else, I tried contacting them several times
