First I got a call from HR, enquired about qualification and experience. After few days they scheduled Technical interview with a senior data scientist. After 1-2 weeks I got an email with a test link. The test was of moderate difficulty - few MCQ s and a modelling problem. After 2 weeks I got a call saying they are scheduling a 3rd level Techno-managerial interview. After that I haven't heard back from the HR.
