Total 4 rounds. 1st is HR, 2nd & 3rd are Technicals, and final interview is a senior manager round. Mine was a graduate level role. 1st HR round was kind of a screening round with basic technicals and behavioural questions. 2nd round was a proper technical round with a focus on DSA, Data Modeling, Taxonomies(bloomberg loves this), Statistics, and little machine learning. 3rd round was mainly a Exploratory Data Analysis round using python and pandas. Final round was a behavioural round with the senior manager. All the interviewers were super awesome. It felt more like a discussion, rather than a interview. All they want is to see you collaborate with them. The HR was super fast with the updates as well. Totally a very smooth experience and I feel really grateful to all the people who interviewed me and coordinated my entire process. Really excited for my joining date.
