A real question from this track
"An executive alerts you that overall Weekly Active Users (WAU) dropped by 12% week-over-week. Walk through your step-by-step exploratory data analysis methodology: how do you systematically decompose the metric across acquisition cohorts, platforms, geography, and feature usage to isolate the primary driver?"
What we evaluate for a Data Analyst role
Technical Fundamentals
SQL fluency (joins, window functions, aggregation), data cleaning and quality checks, descriptive statistics, metric design (funnels, retention, cohorts), dashboarding concepts, and communicating uncertainty. Excel/Sheets reasoning where relevant.
Problem Solving
SQL query-writing problems (top-N per group, dedupe, sessionization), pandas-style data transformations, metric-debugging scenarios (why did this KPI drop), and small case questions requiring back-of-envelope estimation. Never abstract algorithm puzzles.
SQL Round
SQL query-writing problems (top-N per group, dedupe, sessionization, window functions) against realistic reporting schemas, plus ad-hoc query-writing and query-optimization reasoning. Real tables and business questions, never abstract algorithm puzzles.
Case Study Round
Business-sense case: given a vague business question or a metric that moved, walk through how you'd investigate, what data you'd pull, and what decision you'd recommend — includes back-of-envelope estimation and communicating uncertainty to a non-technical stakeholder.
Projects & Behavioral
Analytics project deep-dive: business question behind the analysis, data sourcing and its caveats, how insights changed a decision, stakeholder pushback stories.
HR Round
Motivation for analytics work, communicating with non-technical stakeholders, handling ambiguous asks.
System Design
Analytics pipeline design: event tracking schema, warehouse modeling (star schema, slowly-changing dimensions), batch vs streaming trade-offs, dashboard performance.
