3. What do you think is the most challenging part of this role, and how would you prepare yourself to meet the challenge?

Tip: 데이터 정확성, 다양한 이해관계자, 시스템 이해 등 언급

Sample Answer:

I think the most challenging part is ensuring data accuracy across multiple systems and communicating findings to various stakeholders. To prepare, I would invest time in understanding your data infrastructure and reporting standards. I would also set up a validation process and maintain open communication with end users to ensure insights are both accurate and actionable.

4. The manager sent an Excel file with over 10,000 records tracking specific activities. She wants to know how many of her records are also found in our health information system (from a different data source), how many of her records match what we have, and how many records in her file are unique. How would you approach this task?

Tip:

• 문제 분해 (1. 정제, 2. 일치 여부 판단, 3. 고유값 계산)
• 조인(Join) 전략 설명 (e.g., Inner Join, Left Join)
• 데이터 매칭 기준 명확화 (예: patient ID, service date 등)
• 결과를 이해하기 쉬운 요약 형태로 제공하는 방안도 제시

Sample Answer:

First, I would standardize both datasets to ensure consistent formats — especially for key fields like patient ID, service date, or procedure code. Then, I would use an inner join to find matching records between the manager’s file and our system data, followed by a left join to identify which of her records have no matches — which would be considered unique.

 

To quantify the results, I’d calculate:

• Total matches (records present in both files)
• Total unmatched records (records only in her file)
• Duplicates or near matches if needed (using fuzzy matching or lookup rules)

Depending on the tools available, I’d use either SQL, Power Query in Excel, or Python with pandas for this comparison. Finally, I’d prepare a summary report with counts and possibly a visual chart, so she can easily interpret the results. If needed, I’d also explain potential reasons for mismatches such as formatting inconsistencies or timing differences in data entry.

5. If she says the data analysis seems incorrect, how would you approach that?

Tip: 열린 자세, 문제 재현, 원인 파악

Sample Answer:

I’d thank her for the feedback and ask specific questions to understand her expectations. I would walk through the logic with her, double-check filters or joins, and compare samples from both datasets. If a mistake is found, I’d correct it and explain the resolution clearly to rebuild trust.

6. They want detailed performance data delivered regularly. How would you address that request?

Tip: 자동화, 일정화, 사용자 요구 반영 강조

Sample Answer:

I would work with stakeholders to define key metrics and reporting frequency. Then, I’d build a repeatable report using Power BI or Excel with dynamic filters and slicers. For automation, I’d set up scheduled data refreshes and email subscriptions or export routines to ensure timely delivery.

7. How do you ensure that you’re going above and beyond in your work?

Tip: 주도성, 문제 해결, 개선 제안 등 언급

Sample Answer:

I go beyond by anticipating stakeholder needs before they arise. For example, when building dashboards, I include trendlines and comparisons so they can get deeper insights. I also proactively suggest new KPIs or find ways to improve existing workflows using automation tools.

8. Tell me about a time when you used good judgment or logic to solve a problem on your own.

Tip: STAR 방식 사용

Sample Answer:

(S) At #, I noticed our flow was skipping failed rows. (T) I needed to ensure all errors were visible. (A) I added a failure log to track rejected entries and created a notification system. (R) This allowed us to catch data issues early and improve overall flow reliability.

9. Tell me about a time when you didn’t meet a deadline or expectation. How did you handle it?

Tip: 솔직하게 공유 + 개선 조치 설명

Sample Answer:

(S) During my final project at university, I underestimated the time required for model tuning. (T) I missed the original internal deadline. (A) I immediately informed my team, restructured the timeline, and delegated simpler tasks to others. (R) We submitted it only slightly delayed but with improved accuracy, and I learned to build more buffer time in future planning.

10. How did the conversation go with stakeholders? Did things stay under control?

Tip: 이해관계자 소통 방식 강조

Sample Answer:

I keep conversations solution-focused and transparent. In one instance, when there was a delay in dashboard deployment, I informed stakeholders early, explained the issue, and proposed an interim workaround. They appreciated the transparency and we stayed aligned throughout the process.

11. When you received feedback about your work or actions, what did you learn about yourself?

Tip: 피드백 수용, 성장 강조

Sample Answer:

One piece of feedback I received was to simplify my language when presenting technical content. I learned that effective communication is just as important as technical accuracy. Since then, I always tailor my delivery to the audience, using analogies or visuals to make complex insights more accessible.
