Preparation at Cedar is about demonstrating your ability to navigate the full software development lifecycle. You should focus on articulating your thought process clearly, as our interviewers are as interested in how you arrive at a solution as they are in the solution itself.

Role-related Knowledge – You must be comfortable working across the stack. Ensure you are proficient in your primary languages and frameworks, but also be ready to discuss how front-end and back-end components communicate effectively.

Problem-solving Ability – We look for candidates who can break down ambiguous problems into manageable, logical steps. Practice explaining your trade-offs—why did you choose one data structure over another, or one architectural pattern over another?

Collaboration and Communication – Engineering at Cedar is a team sport. Demonstrate your ability to work with others by being open to feedback during pair programming sessions and showing that you can communicate complex technical concepts to non-technical stakeholders.

Culture Alignment – We are mission-driven. Research our work in healthcare billing and be prepared to discuss why you are passionate about applying your technical skills to improve the patient financial experience.

The interview process at Cedar is designed to be thorough yet respectful of your time. It typically begins with a recruiter screen, followed by a series of technical assessments that include pair programming and system design. We strive to provide a transparent experience where you get to meet various members of our engineering team, ensuring you have a holistic view of our culture and product challenges.

This timeline illustrates the progression from initial screening to final onsite or remote assessment rounds. You should use this structure to pace your preparation, starting with core technical fundamentals and moving toward complex architectural design as you advance. Note that while the core pillars remain consistent, the specific focus of your interviews may shift depending on the seniority of the role and the specific team you are interviewing with.

Technical Proficiency

We evaluate your ability to write production-ready code. Strong performance means writing code that is not only functional but also readable, tested, and efficient.

Be ready to go over:

• Data structures and algorithmic complexity (Big O notation)
• Clean coding practices and design patterns

As a Full Stack Engineer, your primary responsibility is to design, develop, and maintain the features that define the Cedar product suite. You will work closely with product managers and designers to translate user needs into technical specifications. This involves writing high-quality code across both the front-end (typically React or similar modern libraries) and back-end services.

Beyond individual coding tasks, you will participate in code reviews, contribute to architectural discussions, and help refine our engineering processes. You will collaborate with cross-functional teams to ensure that our deployments are seamless and that our systems remain reliable. You are expected to take ownership of features from conception through to deployment and monitoring.

A successful candidate for this role typically possesses a strong foundation in computer science and extensive experience with modern web development stacks.

• Must-have skills: Proficiency in at least one major back-end language (e.g., Python, Java, or Node.js), strong front-end skills (JavaScript/TypeScript, React), and experience with relational databases.
• Nice-to-have skills: Experience with cloud infrastructure (e.g., AWS), familiarity with Docker/Kubernetes, and previous experience in healthcare or fintech domains.
• Experience level: We look for engineers who have a proven track record of shipping and maintaining production-level code. While years of experience are not a strict filter, the ability to demonstrate depth in your work is essential.

Q: How long should I prepare for the technical interviews? A: Most candidates spend 2–4 weeks of focused preparation on data structures, algorithms, and system design. Use this time to brush up on the fundamentals while also reviewing your own past projects.

Q: What differentiates a good candidate from a great one? A: Great candidates don't just solve the problem; they ask clarifying questions, discuss trade-offs, and demonstrate a genuine interest in the "why" behind their technical decisions.

Q: Is the interview process mostly remote or onsite? A: We have adapted our processes to be flexible, often utilizing remote video conferencing for initial screens and technical assessments, with potential for onsite visits depending on the specific role and location requirements.

Q: How does Cedar approach culture fit? A: We look for individuals who are collaborative, humble, and mission-driven. We want to know that you are as committed to the team's success as you are to your own professional growth.

• Think Out Loud: During coding and design rounds, narrating your thought process is critical. If you are stuck, communicate your reasoning rather than staying silent.
• Ask Clarifying Questions: Never jump straight into a solution. Ask about constraints, edge cases, and the primary goal of the feature.
• Be Honest About Your Experience: If you encounter a technology or concept you aren't familiar with, be transparent. We prefer to see how you approach learning new things rather than watching you guess.
• Review Your Resume: Be prepared to dive deep into any project you list on your resume. You should be able to explain the architecture, the challenges, and the outcome of every bullet point.

The Full Stack Engineer role at Cedar is a unique opportunity to apply your technical expertise to a mission that genuinely improves lives. By focusing on your core engineering fundamentals, sharpening your system design skills, and preparing to communicate your thought process clearly, you will be well-positioned to succeed in our interview process.

Remember that our interviews are designed to be a two-way conversation. We are as interested in learning about your potential as we are in assessing your current skills. You can explore additional interview insights, practice questions, and preparation resources on Dataford.
