Octave Software Engineer interview questions & guide 2026

The following questions reflect patterns observed in previous interview cycles. While interviewers may adapt their approach based on your specific background, these categories represent the core areas of assessment.

Technical Design & Architecture

These questions assess your ability to design scalable systems and think critically about the trade-offs in software architecture.

• How would you design a system to handle high-concurrency patient scheduling?
• Describe a time you had to refactor a legacy system; what was your approach to minimizing downtime?

Preparation for Octave requires a balance of rigorous technical practice and the ability to articulate your design decisions clearly. Focus on demonstrating how your technical solutions directly support the business goals of a healthcare-tech company.

Technical Competence – Your ability to write efficient, readable code is non-negotiable. Ensure you are comfortable with your primary language's standard libraries and best practices for testing and documentation.

Architectural Thinking – You will be evaluated on your ability to think beyond the immediate task. Show the interviewer that you consider scalability, security, and maintainability in every design decision you propose.

Problem-Solving & Communication – Because you will work in cross-functional teams, your ability to explain complex technical concepts to non-technical stakeholders is vital. Practice "thinking out loud" during your design and coding sessions.

The interview process at Octave is designed to evaluate both your technical depth and your ability to work within a collaborative, fast-paced environment. You should expect a sequence that begins with a recruiter screen to align on your experience and interests, followed by a conversation with a Hiring Manager to discuss your technical philosophy and team fit.

The technical portion of the process involves a structured assessment that combines architectural design with hands-on implementation. Candidates often find these sessions to be high-pressure due to the time-boxed nature of the tasks. Approach these with a clear plan: prioritize the most critical features first and communicate your progress to the interviewer throughout the session.

This timeline provides a high-level view of the stages you will encounter. Use this to pace your preparation, ensuring you have enough time to review both high-level system design concepts and specific coding challenges before the assessment phase.

System Design

This area tests your ability to translate abstract requirements into concrete technical specifications. You are expected to consider scalability and security from the start.

Be ready to go over:

• Database schema design for sensitive information.
• API security and authentication protocols.

As a Software Engineer, you will be responsible for the end-to-end development cycle of key product features. You will collaborate closely with product managers and clinicians to understand the pain points in current workflows and translate them into technical requirements.

You will spend a significant portion of your time building and maintaining robust APIs, ensuring that the data flow between our services is secure and performant. You are expected to participate in code reviews, contribute to architectural discussions, and mentor junior team members as the engineering organization grows.

A strong candidate for this role possesses a deep understanding of modern web development and a track record of building reliable software.

• Must-have skills: Proficiency in a modern backend language (e.g., Python, Ruby, or Node.js), experience with relational databases, and a solid understanding of RESTful API design.
• Nice-to-have skills: Experience with cloud infrastructure (AWS or GCP), familiarity with HIPAA compliance standards, and previous experience in a high-growth startup environment.
• Soft skills: Clear communication, a proactive approach to problem-solving, and the ability to thrive in an environment where requirements may shift based on user needs.

Q: How can I best prepare for the technical assessment? A: Practice designing small-to-medium scale systems and writing clean, documented code for common backend tasks. Focus on managing your time effectively between the design and implementation phases.

Q: What is the company culture like? A: Octave is a mission-driven organization. Successful engineers are those who are not only technically proficient but also genuinely invested in the impact of their work on mental health outcomes.

Q: Will I receive feedback if I am not selected? A: While we strive to provide a positive candidate experience, please be aware that the volume of applicants sometimes limits our ability to provide detailed, personalized feedback to every candidate.

• Communicate your trade-offs: Whenever you make a design choice, explain why you chose it over other options. This demonstrates depth of thought.
• Clarify requirements: If a prompt seems ambiguous, ask clarifying questions before diving into the code. This is a key skill for real-world engineering.
• Focus on security: Given the nature of our data, always mention security considerations—such as encryption or access control—when discussing system architecture.

The Software Engineer role at Octave is an opportunity to build technology that fundamentally changes how people access mental health care. By focusing on your core engineering fundamentals, mastering the art of system design trade-offs, and demonstrating a deep commitment to our mission, you will be well-positioned to succeed.
