Guide to Business Understanding with Nakul Sharma - SDE II

Most data analyst candidates prepare hard for SQL and Excel, then get caught off guard by the one round that actually decides the offer: the business-case round. t tests how you think, not what you can query.

This guide is built entirely for that round.

Inside, you'll find:

• The FRAME method
• Worked company cases - realistic scenarios modelled on companies like Zepto, Meesho, and PhonePe, each solved fully using FRAME so you can see the reasoning end to end.
• A complete interview case, solved step by step - the classic "traffic went up but conversion dropped" problem, worked through with real numbers, evidence, and a final recommendation.
• An answer template and worksheet - practical tools you can revise right before the interview to keep your answers clear and structured.
• Five practice problems and common mistakes - the exact errors freshers make in these rounds, and how to avoid them.

This is a lean, no-fluff guide: less theory, more interview-ready thinking. It's ideal for freshers and career-switchers who are comfortable with SQL but lack confidence in framing business problems and communicating a recommendation.

Note: this guide focuses specifically on the business-understanding round. You'll still want separate preparation for SQL, Excel, and statistics rounds.
