How to Answer

Explain the fundamental differences in structure, querying, and use cases for both SQL and MongoDB. Highlight the importance of choosing the right database for specific data needs.

Example

“SQL is a relational database that uses structured query language for defining and manipulating data, while MongoDB is a NoSQL database that stores data in flexible, JSON-like documents. SQL is ideal for structured data with relationships, whereas MongoDB is better suited for unstructured data and scalability.”

2. Can you explain how you would optimize a SQL query?

Example

“To optimize a SQL query, I would first analyze the execution plan to identify bottlenecks. Then, I would consider adding indexes on frequently queried columns and rewriting the query to eliminate unnecessary joins. For instance, I once reduced query time by 50% by indexing a key column and restructuring the query to minimize data retrieval.”

3. Describe your experience with SAS in data analysis.

SAS is a common tool in healthcare analytics, and familiarity with it can set you apart.

How to Answer

Handling missing data is a critical skill for any data analyst, especially in healthcare where data integrity is paramount.

How to Answer

Discuss various strategies such as imputation, deletion, or using algorithms that can handle missing values. Provide an example of how you applied one of these methods.

Example

“When faced with missing data, I typically assess the extent and pattern of the missingness. In a recent project, I used mean imputation for a small percentage of missing values, while for larger gaps, I opted for predictive modeling to estimate the missing data based on other variables.”

Industry Knowledge
