There will be a good level puzzle round as written test,followed by 2 tech rounds where they check your technical knowledge basically questions on sql,excel,python (if you include some of these in your cv and the form given by them).But I don't have any technical experience or knowledge so I frankly told them this and they grilled me on my logical approach and problem solving by asking puzzles and case questions and have seen approach towards the sql questions.Final round is with CEO it's an awesome experience he will be asking you some behavioral questions and case questions.All they want is the logical thinking and people who are very talented in all aspects as extracurricular.
