Experience and Background

1. Can you explain your relevant work experience and how it relates to this role?

This question aims to understand your background and how it aligns with the responsibilities of a Data Scientist at NYU Langone Health.

How to Answer

Highlight specific projects or roles that demonstrate your experience with data analysis, statistical methods, and any relevant healthcare applications.

Example

“In my previous role at XYZ Health, I led a project analyzing patient data to identify trends in treatment outcomes. This involved using SQL for data extraction and Python for analysis, which resulted in actionable insights that improved patient care protocols.”

Technical Skills

2. What is a p-value, and how do you interpret it in hypothesis testing?

Understanding statistical concepts is crucial for a Data Scientist, especially in a research-focused environment.

How to Answer

Explain the concept of a p-value and its significance in determining the strength of evidence against the null hypothesis.

Example

“A p-value is a measure that helps us determine the significance of our results in hypothesis testing. A low p-value (typically < 0.05) indicates strong evidence against the null hypothesis, suggesting that the observed data is unlikely under that hypothesis.”

3. Describe a time when you used SQL to solve a data-related problem.

SQL skills are essential for data manipulation and analysis in this role.

How to Answer

Provide a specific example of a problem you solved using SQL, detailing the approach and the outcome.

Data quality is critical in healthcare analytics.

How to Answer

Discuss the methods you use to validate and clean data before analysis.

Example

“I implement a multi-step data validation process that includes checking for missing values, outliers, and inconsistencies. I also use automated scripts to flag anomalies, ensuring that the data I work with is reliable and accurate.”

5. Can you explain a statistical method you have used in a project?

This question assesses your practical knowledge of statistical techniques.

How to Answer

Choose a statistical method relevant to your experience and explain its application in a project.
