5. Deep Dive into Evaluation Areas

Technical Assessment

This usually involves a take-home test focused on SQL and Excel. You will be evaluated on your ability to retrieve data efficiently and organize it into a meaningful format.

Be ready to go over:

• SQL Joins and Aggregations – The bread and butter of your data retrieval process.
• Excel Data Modeling – Creating clean, repeatable reports.

Business Logic and Case Studies

Interviewers want to see how you think through a problem from scratch. They will look for a structured approach that considers all variables before jumping to a conclusion.

Be ready to go over:

• KPI Selection – Defining the right metrics for a specific problem.
• Root Cause Analysis – How you investigate a sudden drop or spike in a metric.
• Marketplace Dynamics – Understanding the balance between supply and demand.

6. Key Responsibilities

As a Business Analyst, your day-to-day will involve maintaining a pulse on the health of the marketplace. You will spend significant time querying databases to extract insights and transforming that data into dashboards or presentations that inform stakeholders.

You will work closely with product and operations teams to identify friction points in the user journey. By quantifying these issues, you help prioritize the engineering roadmap. Your output is the foundation for strategic initiatives, meaning your accuracy and ability to communicate the "so what" behind the data are essential to your success.
