Technical Skills

1. What are the key principles of Object-Oriented Programming (OOP)?

Understanding OOP is crucial for software development, especially in a microservices architecture.

How to Answer

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

Example

“Object-Oriented Programming is built on four key principles: encapsulation, which allows for data hiding; inheritance, which enables code reuse; polymorphism, which allows for method overriding; and abstraction, which simplifies complex systems. In my last project, I used inheritance to create a base class for user authentication, which was then extended by various user types, ensuring a clean and maintainable codebase.”

2. Can you explain microservices architecture and its benefits?

Microservices are a significant part of modern software development, especially at Enel.

How to Answer

Define microservices and discuss their advantages, such as scalability, flexibility, and ease of deployment.

Example

“Microservices architecture involves breaking down applications into smaller, independent services that can be developed, deployed, and scaled individually. This approach enhances scalability and allows teams to work on different services simultaneously, leading to faster development cycles. For instance, in my previous role, we transitioned to a microservices architecture, which improved our deployment frequency by 30%.”

3. How do you approach testing and ensuring the quality of your code?

Quality assurance is vital in software development.

How to Answer

Discuss your testing strategies, including unit tests, integration tests, and any tools you use.

Example

“I prioritize writing unit tests for my code to catch issues early in the development process. I also use integration tests to ensure that different services work together as expected. For example, in my last project, I implemented a CI/CD pipeline that automatically ran tests on every commit, which significantly reduced the number of bugs in production.”

4. Describe your experience with SQL and database modeling.

SQL skills are essential for managing data in software applications.

How to Answer

Talk about your experience with SQL, including specific databases you’ve worked with and any complex queries you’ve written.

Example

“I have over five years of experience working with SQL Server, where I’ve designed and optimized database schemas. I often write complex queries involving joins and stored procedures to extract meaningful insights from data. For instance, I developed a stored procedure that aggregated user activity data, which helped the product team make informed decisions about feature enhancements.”

5. What is your experience with Agile methodologies?

Agile practices are integral to the development process at Enel.

How to Answer

Share your experience with Agile, including specific ceremonies you’ve participated in and your role in the team.

Example

“I have worked in Agile environments for over two years, participating in daily scrums, sprint planning, and retrospectives. I believe that Agile fosters collaboration and adaptability, which are crucial for delivering high-quality software. In my last team, I took on the role of Scrum Master, facilitating meetings and ensuring that our team remained focused on our sprint goals.”

Behavioral Questions

1. Can you describe a challenging project you worked on and how you overcame 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 overcome them.

Example

“In a recent project, we faced significant delays due to unexpected technical debt. I organized a series of meetings to identify the root causes and prioritized refactoring tasks in our backlog. By reallocating resources and focusing on critical issues, we managed to get back on track and successfully delivered the project on time.”

2. How do you handle feedback and criticism?

Understanding how you respond to feedback is important for team dynamics.

How to Answer

Discuss your approach to receiving feedback and how you use it for personal and professional growth.

Example

“I view feedback as an opportunity for growth. When I receive constructive criticism, I take the time to reflect on it and identify areas for improvement. For instance, after receiving feedback on my code reviews, I started to focus more on providing actionable suggestions, which improved the overall quality of our team’s code.”

3. Why do you want to work for Enel?

This question gauges your interest in the company and its mission.

How to Answer

Express your alignment with Enel’s values and how you can contribute to its goals.

4. How do you prioritize tasks when working on multiple projects?

Time management is crucial in a fast-paced environment.

How to Answer

Explain your prioritization strategy and any tools you use to manage your workload.

Example

“I prioritize tasks based on their urgency and impact on project goals. I use tools like Trello to visualize my workload and ensure that I’m focusing on high-priority items. For example, during a recent project, I had to balance multiple deadlines, so I created a priority matrix to help me allocate my time effectively.”

5. Describe a time when you had to work with a difficult team member.

This question assesses your interpersonal skills and ability to navigate conflicts.

How to Answer

Share a specific example, focusing on how you handled the situation professionally.

Example
