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.
