The interview was super easy. Just make sure you're honest on your resume, they'll catch you if you're not. Also, get ready to talk in detail about any projects you listed on your resume, especially if you've actually done them yourself, 'cause that's what they'll ask about.

First, there's an online aptitude test on platforms like Mettl, Cocubes, or AMCAT. It covers Quant (Percentages, Probability, PnC, Time-Speed-Distance, Averages), Logical Reasoning (Puzzles, seating arrangements, series, coding-decoding), Data Interpretation (Tables, graphs, caselets), and Basic Verbal Ability (Grammar, comprehension, critical reasoning). It's 45–60 mins and pretty tough, with only about 15–20% passing. Then, there's a Group Discussion or Case Study. It's usually more of a business case discussion than a debate, like 'A retail chain is facing declining sales. How would you analyze the problem?'. They care about how structured your thinking is, if you're clear, and if you work well in a team, not just about who talks the most. Sometimes, they swap this for a Written Case Study where you have to solve and submit your approach. Next up is the Technical / Case Interview. Here, they check your problem-solving and analytical skills. Expect guesstimate questions like 'How many ATMs are there in India?', business case questions like 'How would you improve revenue for an airline company?', puzzles, logic questions, and some basic stats/probability. Coding isn't the main thing like in product companies, but they might test your basic Excel/SQL knowledge. Finally, the HR / Final Round. This is where they ask typical behavioral questions such as 'Tell me about yourself,' 'Why Mu Sigma?,' 'How do you handle pressure?,' and 'Where do you see yourself in 5 years?'. They're looking to see if you're a good cultural fit, if you're adaptable, and how well you communicate. Basically, they want to see structured problem-solving, the ability to think with numbers and logic, good communication and teamwork, and adaptability because the environment at Mu Sigma can be high-pressure.

So there were 3 rounds of online tests first. After that, there was an AI bot interview, followed by a technical interview and an HR interview. The AI bot focused on my resume. The technical and HR interviews asked about data science stuff. There was also a short discussion about my background, motivation, and general fit, including leadership, teamwork, and problem-solving under stress.
