Rewarding, demanding and exciting interview process. Recruiter guided me before each and every interview rounds. 1st call was with recruiter. It was very basic and questions about my experience and interests. Then 2 Skype interviews (with Hiring manager and senior data science engineer). I had to reschedule my interviews at the last moment due to my vacation but recruiter was very responsive and quick in rescheduling interviews. Then, got a call for an onsite interview with senior engineers of the data science team. They were really nice and patient in asking questions. Each round was very interesting and questions were more around my experience. Mostly ML, statistics and AWS. Some behavioral questions. One of the round was about deriving a mathematical equation for a given scenario and then writing a pseudo code. Lastly, I had a quick call with HR to make sure my visa status and processes. I was presented the verbal offer after 1 day. Overall it was very good experience.
