The interview process involved 1 hacker rank test, 3 interviews with data scientists and 2 with executive leadership. It was extremely efficient and accommodating. HR and the team were very responsive to make any changes to the schedule. The whole process took about 4 weeks.
Hacker rank test was straight-forward, tests on basic machine learning knowledge and programming. Next phase was 2 back to back interviews with the team focused on Machine Learning, problem solving and programming. Next round was with Principal Data Scientist, testing my skills on statistics and machine learning. He also explained about problems they are working on, company culture and work. They were very friendly, smart and overall it was a very pleasant experience.
I was scheduled the next 2 rounds of interviews with executive leadership next week. They were mainly focused on role and cultural fit.
