Understanding database types is crucial for a software engineer, especially in a healthcare context where data management is vital.

How to Answer

Discuss the fundamental differences in structure, scalability, and use cases for SQL and NoSQL databases. Highlight scenarios where one might be preferred over the other.

Example

“SQL databases are relational and use structured query language for defining and manipulating data, making them ideal for complex queries. In contrast, NoSQL databases are non-relational and can handle unstructured data, which is beneficial for applications requiring high scalability and flexibility, such as real-time analytics.”

2. Can you explain the adapter design pattern and provide an example of how you've used it?

This question tests your understanding of design patterns and their practical applications.

How to Answer

Define the adapter design pattern and explain its purpose in software development. Provide a specific example from your experience where you implemented this pattern.

Example

“The adapter design pattern allows incompatible interfaces to work together. I used it in a project where I needed to integrate a legacy system with a new application. By creating an adapter, I was able to facilitate communication between the two systems without modifying their existing codebases.”

3. Describe your experience with Java and how it compares to other programming languages you’ve used.

Given that Sidecar Health primarily uses Java, they will want to assess your proficiency in this language.

How to Answer

Discuss your experience with Java, including specific projects or applications you've developed. Compare it to other languages you know, focusing on strengths and weaknesses.
