First round was a one way interview where i was asked about 5 questions like tell me about a time when 'XYZ'. Next round was with the HR(basic qualification questions including experience with certain tech stack). Next round was a one hour technical interview where i was first asked to explain a project of mine and then asked questions on it. Later on, i was also asked a few basic ML, Statistics, big data questions. After that i had a super day where i had 3 rounds- 1 behavioural style, a 2 hour technical data science case study(Kaggle styled) and just after that a 45 minute interview with tech lead explaining my approach and getting asked different questions on that.
