In this section, we’ll review the various interview questions that might be asked during a Software Engineer interview at Doximity. The interview process will likely focus on your technical skills, problem-solving abilities, and cultural fit within the company. Be prepared to discuss your experience with Ruby on Rails, Python, SQL, and your approach to software engineering best practices.

Technical Skills

1. Can you explain the MVC architecture and how it applies to Ruby on Rails?

Understanding the Model-View-Controller (MVC) architecture is crucial for any Rails developer.

How to Answer

Discuss the roles of each component in the MVC architecture and how they interact with each other in a Rails application.

Example

“The Model represents the data and business logic, the View is the user interface, and the Controller handles the input and updates the Model. In Rails, this separation allows for cleaner code and easier maintenance, as each component can be developed and tested independently.”

2. What are some common performance optimizations you can implement in a Rails application?

Performance is key in web applications, and knowing how to optimize is essential.

How to Answer

Mention specific techniques such as caching, eager loading, and database indexing.

Example

“Some common optimizations include using fragment caching to store parts of views that don’t change often, eager loading associations to avoid N+1 queries, and ensuring proper database indexing to speed up query performance.”

3. How do you handle versioning in APIs?

Versioning is important for maintaining backward compatibility in APIs.

How to Answer

Explain different strategies for API versioning, such as URL versioning or header versioning.

Example

“I typically use URL versioning, where the version number is included in the endpoint, like /api/v1/resource. This approach makes it clear which version of the API is being accessed and allows for easier management of changes over time.”

4. Describe a time you implemented a design pattern in your code. Which pattern did you use and why?

Design patterns help in writing reusable and maintainable code.

How to Answer

Choose a specific design pattern, explain its purpose, and describe how you implemented it.

Example

“I used the Observer pattern in a notification system where different parts of the application needed to be updated when a user performed an action. This allowed for a decoupled architecture, making it easier to add new features without modifying existing code.”

5. What is your approach to testing in a Rails application?

Testing is vital for ensuring code quality and reliability.

How to Answer

Discuss your experience with testing frameworks and your approach to writing tests.

Example

“I use RSpec for unit and integration testing in Rails. I believe in writing tests alongside the code to ensure that new features are covered and existing functionality remains intact. I also prioritize writing feature tests to simulate user interactions.”

Problem Solving

1. How would you troubleshoot a performance issue in a Rails application?

Troubleshooting skills are essential for maintaining application performance.

How to Answer

Outline a systematic approach to identifying and resolving performance issues.

Example

“I would start by monitoring the application’s performance metrics using tools like New Relic or Skylight. Then, I would analyze slow queries in the database, check for N+1 queries, and review the application logs for any errors or bottlenecks.”

2. Can you 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, describe the challenge, and explain your thought process in resolving it.

Example

“I faced a challenge with a feature that required real-time updates. I implemented ActionCable to handle WebSocket connections, allowing the application to push updates to users without requiring them to refresh the page. This significantly improved user experience.”

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

Time management and prioritization are key in a fast-paced environment.

How to Answer

Discuss your approach to prioritizing tasks based on urgency and impact.

Example

“I use a combination of Agile methodologies and tools like Trello to manage my tasks. I prioritize based on deadlines and the potential impact on the project. Regular check-ins with my team also help ensure alignment on priorities.”

4. What strategies do you use to ensure code quality?

Maintaining high code quality is essential for long-term project success.

How to Answer

Mention practices such as code reviews, pair programming, and adherence to coding standards.

Example

“I advocate for regular code reviews and pair programming sessions to catch issues early and share knowledge within the team. Additionally, I follow established coding standards and use linters to maintain code quality.”

5. How would you approach building a new feature from scratch?

This question assesses your project management and development skills.

How to Answer

Outline your process from ideation to deployment.

Example

“I would start by gathering requirements from stakeholders and defining the feature’s scope. Next, I would create a design document outlining the architecture and implementation plan. After that, I would develop the feature iteratively, testing as I go, and finally deploy it with thorough documentation for future reference.”
