Workday Software Engineer Interview Questions

In this section, we’ll review the various interview questions that might be asked during a Software Engineer interview at Workday. The interview process will likely assess your technical skills, problem-solving abilities, and cultural fit within the company. Be prepared to discuss your past experiences, technical knowledge, and how you approach challenges in software development.

Technical Skills

1. Can you explain the principles of Object-Oriented Programming (OOP) and how they apply to your work?

Understanding OOP is crucial for a software engineer, as it forms the foundation of many programming languages and design patterns.

How to Answer

Discuss the four main principles: encapsulation, inheritance, polymorphism, and abstraction. Provide examples of how you’ve applied these principles in your projects.

Example

“OOP principles guide my approach to software design. For instance, I used encapsulation to hide the internal state of an object in a recent project, ensuring that the object’s data could only be modified through well-defined methods. This improved security and made the code easier to maintain.”

2. Describe your experience with database technologies, particularly MySQL and PostgreSQL.

Given Workday’s focus on database services, familiarity with these technologies is essential.

How to Answer

Highlight your hands-on experience with these databases, including any specific projects where you designed or optimized database schemas.

Example

“I have over five years of experience working with MySQL and PostgreSQL. In my last role, I designed a database schema for a web application that handled thousands of transactions daily, optimizing queries to improve performance by 30%.”

3. What is your approach to writing APIs, and can you provide an example of an API you developed?

APIs are critical for integrating services and enhancing functionality.

How to Answer

Discuss your experience with RESTful APIs, including the design process and any tools or frameworks you used.

Example

“I designed a RESTful API for a microservices architecture that allowed different services to communicate efficiently. I used Swagger for documentation, which made it easier for other developers to integrate with our services.”

4. How do you ensure the security and performance of your applications?

Security and performance are paramount in software development, especially in a cloud environment.

How to Answer

Talk about specific practices you follow, such as code reviews, performance testing, and using security frameworks.

Example

“I implement security best practices by conducting regular code reviews and using tools like OWASP ZAP for vulnerability scanning. For performance, I utilize profiling tools to identify bottlenecks and optimize critical paths in the code.”

5. Can you explain the importance of continuous integration/continuous deployment (CI/CD)?

CI/CD is a key practice in modern software development that enhances collaboration and efficiency.

How to Answer

Define CI/CD and discuss how you have implemented these practices in your previous roles.

Example

“CI/CD allows for frequent code changes and automated testing, which reduces integration issues. In my last project, I set up a CI/CD pipeline using Jenkins, which automated our testing and deployment processes, leading to a 40% reduction in release time.”

Behavioral Questions

6. Describe a challenging project you worked on and how you overcame the obstacles.

This question assesses your problem-solving skills and resilience.

How to Answer

Choose a specific project, outline the challenges faced, and explain the steps you took to resolve them.
