The process took months. I applied in Feb 2019 through referral and got call in April. Initial phone screen with HR and then technical screening with the hiring manager. The HR was always proactive throughout the process. However, the conversation woth the hiring manager was not so interactive. He was not happy with me for using different algorithm in my previous experience for a problem. It was clear from his tone that he want only one way to solve the problem. Though after mentioning that I would like to know more about solving that in your way. I was rejected after the phone screen.

General Phone screening and multiple round interviews. Wasn't too hard but ask a lot of parallel questions. Make sure you know the differences between data science, data/business analytics, and data engineer.
