It was comprised of three rounds:
1.written coding test of python.
2.First round of Interview in python.
3. Second round of interview in AI/ML.
Written test was quite hard and not at all related to data scientist profile. There were questions mostly related to class, inheritance, dictionaries. No data related programming questions. No numpy,no pandas, no lambdas. After that in interview, they ask me questions related to linux, servers, inheritance, to design a software, API related questions which is very irrelevant for this profile.
