Experience and Background

1. Describe your experience with data analysis and how it has prepared you for this role.

This question aims to assess your background and how it aligns with the responsibilities of a Business Analyst at Flatiron Health.

How to Answer

Highlight specific projects or experiences where you utilized data analysis to drive decisions or insights. Emphasize your familiarity with relevant tools and methodologies.

Example

“In my previous role, I worked on a project analyzing patient data to identify trends in treatment outcomes. I utilized SQL for data extraction and R for statistical analysis, which led to actionable insights that improved patient care protocols.”

Technical Skills

2. Can you explain the difference between inner join and outer join in SQL?

Understanding SQL joins is crucial for data manipulation and analysis.

How to Answer

Clearly define both types of joins and provide examples of when each would be used in a data analysis context.

Example

“An inner join returns only the rows where there is a match in both tables, while an outer join returns all rows from one table and the matched rows from the other. For instance, if I have a table of patients and a table of treatments, an inner join would show only patients who received treatments, whereas an outer join would show all patients, including those who did not receive any treatments.”

3. Describe a time when you had to analyze a large dataset. What tools did you use?

This question assesses your practical experience with data analysis tools and techniques.

How to Answer

Discuss the dataset, the tools you used, and the insights you derived from your analysis.

Example

“I once analyzed a dataset of over 100,000 patient records using Python and Pandas. I performed data cleaning, exploratory data analysis, and visualizations to identify patterns in patient demographics and treatment efficacy, which informed our clinical strategies.”

4. How would you approach designing a database schema for a new project?

This question evaluates your understanding of database design principles.

How to Answer

Outline the steps you would take to gather requirements, identify entities, and establish relationships.

Example

“I would start by gathering requirements from stakeholders to understand the data needs. Then, I would identify key entities, such as patients, treatments, and outcomes, and define their relationships. Finally, I would create an ER diagram to visualize the schema before implementation.”

5. What is your experience with data visualization tools? Which do you prefer and why?

This question gauges your familiarity with data visualization and your ability to communicate insights effectively.

How to Answer

Mention specific tools you have used and explain why you prefer one over the others based on your experiences.

Example

“I have experience using Tableau and Power BI for data visualization. I prefer Tableau for its user-friendly interface and powerful capabilities in creating interactive dashboards, which I find effective for presenting data to non-technical stakeholders.”

Problem-Solving and Critical Thinking

6. Describe a challenging analytical problem you faced and how you solved it.

This question assesses your problem-solving skills and ability to think critically.

How to Answer

Provide a specific example of a challenge, the steps you took to address it, and the outcome.

Example

“I encountered a situation where the data I was analyzing had significant missing values. I implemented a combination of imputation techniques and sensitivity analysis to assess the impact of the missing data on my results. This approach allowed me to provide reliable insights while acknowledging the limitations of the dataset.”

7. How do you prioritize tasks when working on multiple projects?

This question evaluates your time management and organizational skills.

How to Answer

Discuss your approach to prioritization, including any frameworks or tools you use.

Example

“I prioritize tasks based on their urgency and impact. I often use a priority matrix to categorize tasks and focus on high-impact activities first. Additionally, I communicate regularly with stakeholders to ensure alignment on priorities.”

8. Can you give an example of how you have influenced a decision based on your analysis?

This question looks for evidence of your ability to drive change through data.

How to Answer

Share a specific instance where your analysis led to a significant decision or change.

Example

“During a project analyzing patient readmission rates, I discovered a correlation between certain treatment plans and higher readmission rates. I presented my findings to the clinical team, which led to a revision of the treatment protocols, ultimately reducing readmission rates by 15%.”

9. What methods do you use to ensure data quality and integrity?

This question assesses your understanding of data governance and quality assurance.

How to Answer

Discuss specific practices you follow to maintain data quality.

Example

“I implement data validation checks during data entry and regularly conduct audits to identify discrepancies. Additionally, I advocate for standardized data entry procedures to minimize errors and ensure consistency across datasets.”

10. How do you stay updated with the latest trends in data analysis and healthcare analytics?

This question evaluates your commitment to professional development and staying informed.

How to Answer

Mention specific resources, communities, or courses you engage with to keep your skills current.

Example

“I regularly read industry publications, participate in webinars, and am a member of several professional organizations focused on healthcare analytics. I also take online courses to learn new tools and techniques that can enhance my analytical capabilities.”
