Preparation for a Software Engineer role at Ceribell requires a strategic approach. Do not merely review algorithms; focus on the why behind your technical decisions. We value candidates who can articulate the business impact of their engineering choices.

Technical Proficiency – You must demonstrate a mastery of your chosen language and foundational computer science concepts. Interviewers will push you to explain the underlying mechanics of your code and how you ensure it remains robust in production.

System Design Thinking – We expect you to think beyond the immediate task to the broader architecture. You should be comfortable discussing scalability, concurrency, and the trade-offs inherent in distributed systems.

Communication and Clarity – As you will work with cross-functional teams, your ability to explain technical concepts to non-technical partners is paramount. Use the STAR method (Situation, Task, Action, Result) to keep your behavioral answers structured and impactful.

Alignment with Mission – We are solving real-world medical challenges. Showing genuine interest in our product and the clinical problems we solve will set you apart.

The interview journey at Ceribell is structured to be thorough, providing you with ample opportunity to demonstrate your skills while giving you a clear view of our team culture. The process is designed to assess you across multiple dimensions, including technical depth, architectural vision, and collaborative potential.

You will typically progress through a series of stages that include an initial recruiter screen, followed by technical deep-dives with engineering peers and leadership. We prioritize a balance of coding assessments, system design discussions, and scenario-based presentations. We believe in transparency and strive to keep you informed of your status throughout the process.

This timeline illustrates the progression from initial screening to final leadership reviews. Use this to pace your study—prioritize technical fundamentals early on, and save time for refining your presentation skills and practicing behavioral scenarios as you reach the later stages.

System Architecture and Scalability

We test your ability to build systems that scale. We are less concerned with "textbook" answers and more interested in how you handle real-world constraints.

Be ready to go over:

• Concurrency models and how to manage high-thread environments.
• Database sharding and partitioning strategies for large datasets.
• Caching layers and their impact on system performance.

Example scenarios:

• "Design a real-time data ingestion pipeline for our EEG devices."
• "How would you handle a sudden spike in traffic that threatens system stability?"

Code Quality and Maintainability

Your code represents our product's reliability. We look for clean, documented, and testable implementations.

Be ready to go over:

• Refactoring strategies for legacy codebases.
• Dependency management and decoupling logic.
• Testing methodologies (unit, integration, and end-to-end).

Example scenarios:

• "Walk me through how you would refactor this module to improve its SOLID compliance."
• "How do you decide when to introduce a new design pattern versus keeping the solution simple?"

As a Software Engineer, you will be responsible for the end-to-end development of features that drive our platform forward. You will work closely with the product and engineering teams to translate high-level requirements into scalable, reliable code.

You will spend a significant portion of your time designing and implementing backend services, ensuring they are optimized for performance and maintainability. Collaboration is key; you will often engage with the supply chain or data engineering teams to integrate hardware-software workflows. You will also participate in architectural reviews, where your ability to defend your design choices and consider long-term implications will be essential.

We look for engineers who bring a blend of deep technical expertise and a pragmatic, solution-oriented mindset.

• Must-have skills: Strong proficiency in a modern backend language (e.g., Java, Python, or Go), deep understanding of OOPS and design patterns, and proven experience in building scalable distributed systems.
• Nice-to-have skills: Experience in medical device software, familiarity with real-time data processing, and previous work in highly regulated environments.
• Experience level: We value depth of experience; successful candidates typically possess a solid background in delivering production-grade software in fast-paced environments.

Q: How should I prepare for the presentation round? Focus on clarity and logical flow. We want to see how you break down a complex business problem, identify the technical bottlenecks, and propose a phased implementation plan.

Q: Is the interview process mostly remote or onsite? The process often involves a mix of virtual screens and an onsite component. Expect to spend significant time (often several hours) during the onsite stage engaging with various team members.

Q: How long should I expect the entire process to take? While we strive for efficiency, the process is thorough and can span several weeks, especially when coordinating with leadership for final rounds.

Q: What differentiates successful candidates? Successful candidates demonstrate a "can-do" attitude, a deep curiosity about our medical domain, and the ability to articulate the trade-offs of their technical decisions clearly.

• Own your resume: Every line on your resume is fair game. If you list a technology, be prepared to discuss its pros, cons, and why you chose it over alternatives.
• Focus on the 'Why': When discussing your past work, don't just explain what you built—explain why you built it that way and what the outcome was.
• Practice whiteboarding: Even in remote settings, be ready to sketch out system architectures and explain your thought process in real-time.
• Ask insightful questions: Use the time at the end of each interview to ask about the team’s current technical challenges; this shows you are already thinking like a member of the team.

The Software Engineer role at Ceribell offers a unique opportunity to apply high-level engineering skills to life-saving technology. By focusing on your core technical foundations, mastering system design principles, and clearly communicating your past contributions, you can position yourself as a strong candidate.

Remember that every interview is an opportunity to showcase your problem-solving process. Prepare thoroughly, stay engaged, and approach each interaction with the confidence of an engineer who understands both the complexity of the code and the importance of the mission.
