What is a Software Engineer at Resmed?

Resmed is a global leader in digital health and cloud-connected medical devices, focused on transforming care for people with sleep apnea, COPD, and other chronic diseases. As a Software Engineer at Resmed, you are not simply writing code; you are building the digital backbone that supports millions of connected devices and improves patient outcomes worldwide.

The engineering culture at Resmed sits at the intersection of healthcare, hardware, and high-scale cloud computing. You will work on products ranging from embedded device software to massive cloud platforms that process health data. The role demands a high level of responsibility because the software you build directly impacts the quality of life for patients. You will join teams that value precision, reliability, and innovation, contributing to a tech ecosystem that is rapidly modernizing the medical device industry.

Common Interview Questions

Getting Ready for Your Interviews

Preparation for Resmed requires a balance of core computer science fundamentals and specific technology stack expertise. Unlike some generalist tech companies, Resmed teams often look for proficiency in the specific tools they use to maintain their critical healthcare systems.

You will be evaluated on the following key criteria:

Technical Specificity and Depth – Resmed interviewers often drill down into specific technologies (such as .NET, AWS, or SQL) rather than sticking solely to abstract algorithmic concepts. You must demonstrate that you understand the "how" and "why" of the tools you use, not just the theory.

Domain Awareness and Quality Focus – Given the medical nature of the business, there is a premium on code quality, testing, and reliability. You should demonstrate a mindset that prioritizes robust, maintainable solutions over quick fixes.

Communication and Cultural Fit – You will likely face behavioral questions that assess your ability to work in cross-functional teams. Interviewers look for candidates who are transparent, patient, and capable of explaining technical concepts to non-technical stakeholders.

Interview Process Overview

The interview process at Resmed is generally structured to assess both your technical capabilities and your alignment with the company’s mission. While the experience can vary significantly by location (e.g., San Diego, Sydney, Halifax, or Bangalore), the general flow remains consistent. Candidates often describe the process as straightforward, though the timeline can vary from a rapid two-week turnaround to a longer process requiring patience.

You should expect a multi-stage process that begins with a screening layer. This often involves a recruiter phone screen or an automated video interview (HireVue), where you record answers to pre-set questions. Following this, you will move into technical assessments. Depending on the team, this may be an online coding/MCQ exam or a direct interview with a hiring manager.

The final stages typically involve a series of back-to-back interviews (often virtual) with the engineering team, managers, and occasionally a director or HR business partner. These sessions dive deep into your technical background and behavioral competencies. It is worth noting that some candidates have reported that specific teams can be quite rigid regarding their preferred tech stack, so flexibility and deep preparation in the required languages are essential.

The visual timeline above outlines the typical progression from your initial application to the final offer. Use this to gauge where you are in the pipeline; if you are asked to complete a HireVue or online assessment, treat it with the same seriousness as a live interview, as it is a critical gatekeeper to the face-to-face rounds.

Deep Dive into Evaluation Areas

Resmed’s technical evaluation is grounded in practical software engineering skills. Based on candidate reports, you should prepare for a mix of fundamental concepts and specific framework questions.

Core Technologies: .NET, OOP, and SQL

For many teams at Resmed, the Microsoft stack is central. You must be comfortable with Object-Oriented Programming (OOP) principles and their application in real-world scenarios. Be ready to go over:

• OOP Fundamentals – Inheritance, polymorphism, encapsulation, and abstraction. Expect questions that ask you to apply these to a design problem.
• .NET Ecosystem – Deep knowledge of C# or .NET basics is frequently tested. You may be asked about memory management, garbage collection, or specific framework features.
• Database Management – SQL proficiency is a common topic. Be prepared to write queries, understand joins, and discuss database normalization.

Cloud & Infrastructure (AWS)

As Resmed relies heavily on cloud connectivity for its devices, cloud competency is a major evaluation area. Be ready to go over:

• AWS Services – Familiarity with core services like EC2, S3, Lambda, and DynamoDB.
• Serverless Architecture – Understanding how serverless functions interact with other cloud components.
• Scalability – How to design systems that handle data from millions of connected devices.

Coding & Problem Solving

While not always "LeetCode hard," the coding rounds are designed to test your logic and coding hygiene. In some regions (like India), this may take the form of an initial exam with MCQs and coding problems. Be ready to go over:

• Data Structures – Arrays, lists, trees, and maps.
• Practical Coding – Writing clean, compilable code to solve a defined logic problem.
• Debugging – Identifying issues in a provided snippet of code.

Behavioral & Situational

Resmed uses behavioral interviews to gauge your fit within their collaborative, patient-focused culture. Be ready to go over:

• Project Experience – "Tell me about a time you faced a technical challenge."
• Team Dynamics – Handling conflict with a peer or pushing back on a requirement.
• Motivation – Why you want to work in the medical device industry specifically.
