In this section, we’ll review the various interview questions that might be asked during a Software Engineer interview at Apixio. The interview process will likely focus on your technical skills, problem-solving abilities, and cultural fit within the company. Be prepared to discuss your past projects, demonstrate your coding skills, and showcase your understanding of software development principles.

Technical Skills

1. Can you explain the differences between REST and SOAP APIs?

Understanding the distinctions between these two types of APIs is crucial for a software engineer, especially in a role that involves developing RESTful APIs.

How to Answer

Discuss the architectural styles, the protocols used, and the advantages and disadvantages of each. Highlight your experience with RESTful APIs, as this is particularly relevant to the role.

Example

"REST APIs are stateless and use standard HTTP methods, making them lightweight and easy to use. In contrast, SOAP APIs are protocol-based and require more overhead, which can make them less efficient. I have primarily worked with REST APIs in my previous projects, focusing on their scalability and ease of integration."

2. Describe your experience with C# and the .NET framework.

C# and .NET are essential technologies for this role, so be ready to discuss your proficiency and experience.

Debugging is a critical skill for any software engineer, and your approach can reveal your problem-solving capabilities.

How to Answer

Outline your systematic approach to debugging, including tools and techniques you use to identify and resolve issues.

Example

"When debugging, I first try to reproduce the issue consistently. I then use logging and debugging tools to trace the problem. For instance, in a recent project, I encountered a performance bottleneck, and by analyzing the logs, I identified an inefficient database query that I optimized, resulting in a significant speed improvement."

4. Can you discuss your experience with SQL and optimizing queries?

SQL skills are vital for this role, especially for writing and optimizing stored procedures.

How to Answer

Share your experience with SQL, focusing on specific optimizations you've made in past projects.

Example

"I have extensive experience with SQL, particularly in writing and optimizing stored procedures. In one project, I optimized a complex query that was taking too long to execute by adding appropriate indexes, which reduced the execution time from several seconds to under one second."

5. What is your experience with Agile methodologies?
