Had a technical interview which involved basic algorithmic coding and machine learning questions. Then had another interview with hiring manager, in which we talked about the role and also some technical questions related to machine learning and my research.
I applied through an employee referral. The process took 5 weeks. I interviewed at A9.com (Palo Alto, CA)

Had 2 phone screens and then on onsite. Onsite consisted of 5 interviews. Most of the interviewers focused on Machine Learning concepts with only 1 or 2 coding related questions overall.
Interview questions [1]
Question 1
The interviewers are smart but super nice too. The questions aren't too difficult if your ML fundamentals are clear (incase you're unsure you'll find out yourself after the interview). Coding questions were easy-medium (harder side of medium) level.
