Summary

Samsung data analyst interview with a single scenario-based case question about planning a parking lot for a Best Buy store. Pretty open-ended, which I didn't expect for a DA role. No coding, just structured thinking.

Questions Asked (1)

Q1

You're working at Best Buy and have been asked to plan a new parking lot for a specific store. What data would you collect to make decisions about its size, layout, and operating policies?

I went straight to foot traffic and peak hours because that felt obvious, but I stalled a bit when trying to connect data sources to actual decisions.

Suggested Approach

Start by clarifying the business objective and constraints (e.g., store size, location, customer traffic patterns). Then outline a data collection plan that covers demand drivers, physical constraints, and operational goals, and finally explain how you would use that data to determine size, layout, and policies.

Pro tip: Frame your answer around the trade-off between customer experience and operational efficiency, and mention that you would validate assumptions with a pilot or A/B test before full implementation.

1. Clarify Objectives and Constraints

Ask questions to understand the store's goals (e.g., maximize customer throughput, minimize wait times) and any physical or budget constraints. This ensures your data collection is focused and relevant.

2. Identify Key Data Categories

Break down data needs into three areas: demand (customer traffic, peak hours), supply (available space, budget), and operations (parking duration, turnover). This structured approach ensures comprehensive coverage.

3. Specify Data Sources and Collection Methods

For each data category, list specific sources (e.g., historical sales, traffic counters, surveys) and methods (e.g., manual counts, sensors, POS data). Explain how you would collect and validate the data.

4. Analyze Data to Inform Decisions

Describe how you would use the data to determine parking lot size (e.g., peak demand analysis), layout (e.g., traffic flow simulation), and policies (e.g., time limits based on average shopping duration).

5. Validate and Iterate

Propose a pilot or phased rollout to test assumptions and gather feedback, then adjust the design and policies based on real-world performance.

Key Points to Mention

  • Customer traffic patterns (daily, weekly, seasonal) and peak hours
  • Average shopping duration and parking turnover rate
  • Competitor or industry benchmarks for parking ratios
  • Physical constraints (lot dimensions, entry/exit points, accessibility requirements)
  • Operational policies (e.g., time limits, validation, EV charging, employee parking)
  • Cost-benefit analysis of different layout options (e.g., angled vs. straight parking)
