HR took extremely long, 1 month after resume submission to send OA, one more month afterwards to advance to round 1 interviews. My round 1 interview was generally pleasant, but during case study portion, the interviewer kept bombarding me with rebuttals to my answers which is fair because they want to see how you work under pressure but just quite nerve wreaking esp because the topic isn't something I'm not familiar with.

1st round , project discussion . 2nd round they wanted to know if u have any deployment idea or not . They want that , u must be able to build AI models and should have idea of deployment.
