Digital Waffle Software Engineer Interview Questions

In this section, we’ll review the various interview questions that might be asked during a Software Engineer interview at Digital Waffle. The interview will likely focus on your technical skills, problem-solving abilities, and your experience with the technologies mentioned in the job descriptions. Be prepared to demonstrate your knowledge of C#, .NET Core, APIs, SQL, and cloud services like Azure, as well as your ability to work collaboratively in a team environment.

Technical Skills

1. Can you explain the differences between .NET Framework and .NET Core?

Understanding the distinctions between these frameworks is crucial for a Software Engineer role at Digital Waffle.

How to Answer

Discuss the key differences in terms of platform compatibility, performance, and deployment options. Highlight the advantages of .NET Core, especially in cloud environments.

Example

“.NET Core is a cross-platform framework that allows for greater flexibility in deployment, while the .NET Framework is Windows-only. .NET Core also offers improved performance and is more suitable for microservices architecture, which is essential for modern SaaS applications.”

2. Describe your experience with Entity Framework. How do you optimize queries?

Entity Framework is a key technology for data access in .NET applications.

How to Answer

Share specific examples of how you've used Entity Framework in past projects, focusing on optimization techniques like eager loading, lazy loading, and using compiled queries.

Example

“I have used Entity Framework extensively to manage database interactions. To optimize queries, I often use eager loading to reduce the number of database calls and implement compiled queries for frequently executed operations, which significantly improves performance.”

3. How do you handle version control in your projects?

Version control is essential for collaborative development.

How to Answer

Discuss your experience with version control systems, particularly Git, and how you manage branches, merges, and pull requests.

Example

“I use Git for version control, following a branching strategy that includes feature branches for new developments and a develop branch for integration. I ensure that all code is reviewed through pull requests before merging to maintain code quality.”

4. Can you explain how you would design a RESTful API?

APIs are a critical component of modern software applications.

How to Answer

Outline the principles of RESTful API design, including resource identification, statelessness, and the use of standard HTTP methods.

Example

“When designing a RESTful API, I focus on resource-based URLs, using GET, POST, PUT, and DELETE methods appropriately. I ensure that the API is stateless and returns meaningful HTTP status codes to indicate the result of operations.”

5. What strategies do you use for debugging and troubleshooting in your applications?

Debugging skills are vital for a Software Engineer.

How to Answer

Share your approach to identifying and resolving issues, including tools and techniques you use.

Example

“I typically start debugging by reproducing the issue and using logging to gather information. I also utilize debugging tools in Visual Studio to step through the code and identify where things go wrong. Additionally, I write unit tests to catch issues early in the development process.”

Problem-Solving and Design

1. Describe a challenging technical problem you faced and how you solved it.

This question assesses your problem-solving skills and resilience.

How to Answer

Choose a specific example that highlights your analytical skills and the steps you took to resolve the issue.

Example

“In a previous project, we faced performance issues with a database query that was slowing down the application. I analyzed the query execution plan, identified missing indexes, and implemented them, which improved the query performance by over 50%.”

2. How do you ensure the quality of your code?

Quality assurance is crucial in software development.

How to Answer

Discuss your practices for writing clean, maintainable code, including code reviews, testing, and documentation.

Example

“I ensure code quality by adhering to coding standards and conducting regular code reviews with my team. I also write unit tests for critical components and maintain thorough documentation to facilitate understanding and future maintenance.”

3. Can you explain the concept of Dependency Injection and its benefits?

Dependency Injection is a key design pattern in modern software development.

How to Answer

Define Dependency Injection and discuss its advantages, particularly in terms of testability and maintainability.

Example

“Dependency Injection is a design pattern that allows a class to receive its dependencies from an external source rather than creating them internally. This promotes loose coupling, making the code easier to test and maintain, as dependencies can be easily swapped out.”

4. How do you approach learning new technologies or frameworks?

Continuous learning is essential in the tech industry.

How to Answer

Share your strategies for staying updated with new technologies, including resources and methods you use.

Example

“I regularly follow tech blogs, participate in online courses, and attend webinars to learn about new technologies. I also enjoy experimenting with new frameworks in personal projects to gain hands-on experience.”
