Very elaborate and lengthy process (lasted 4 months in total). The scope of the interview kept changing as one progresses. Had only 1 round of technical interview and 3 rounds of case studies. Local language is a must even if you are trying for a super technical role.

I appeared for 2 rounds. Selection was based on a case study like assignment submission. 2 Data Scientist were present in the 1st round and question related to Tree based algorithm used in the case study and Overfitting were asked. Price changes with relation to sales data changes with feature isolation was asked. In the 2nd Interview a senior manager was there. Good amount of time was spent on ice breaking and questions related to role and then a case study with Marketing mix model about a Tourism agency was asked.
