1. What is a Software Engineer?

At Cohere, the Software Engineer role is central to the mission of transforming healthcare through intelligent automation and data interoperability. Unlike standard engineering roles where the focus might be solely on traffic scalability, engineers here tackle complex, domain-specific challenges involving prior authorization, clinical intelligence, and patient journey optimization. You are not just writing code; you are building the infrastructure that allows patients to access care faster and helps providers make data-driven decisions.

You will work on a modern technology stack—often involving Python, TypeScript/React, and Java/Kotlin—to build distributed systems and AI-driven platforms. The work requires a deep understanding of reliability and compliance, as the software directly impacts healthcare outcomes. Whether you are focusing on Application Engineering, Platform Infrastructure, or Integrations, your contributions will enable the seamless flow of critical health data between payers, providers, and third-party systems.

2. Common Interview Questions

These questions are based on real interview experiences from candidates who interviewed at this company. You can practice answering them interactively on Dataford to better prepare for your interview.

3. Getting Ready for Your Interviews

Preparation for Cohere requires a shift in mindset from purely algorithmic puzzle-solving to practical, production-ready engineering. You should approach the process as if you are already a member of the team, demonstrating how you balance technical trade-offs with business requirements.

Key Evaluation Criteria:

Technical Proficiency & Code Quality Interviewers look for clean, maintainable, and well-tested code. Given the regulated nature of healthcare, "hacky" solutions are generally viewed negatively. You must demonstrate an ability to write production-grade software that adheres to best practices in CI/CD and observability.

System Design & Scalability For mid-to-senior roles, you will be evaluated on your ability to design distributed systems that are secure, performant, and compliant. You should be able to discuss how to build reusable integration patterns and handle high-volume data ingestion while ensuring data privacy (HIPAA compliance).

Domain Aptitude & Problem Solving While prior healthcare experience is not always mandatory, you must show an aptitude for understanding complex workflows. You will be assessed on how you structure ambiguous problems and whether you can design solutions that satisfy strict requirements from bodies like NCQA or CMS.

Collaboration & Cultural Alignment Cohere values engineers who act as "multipliers"—those who mentor others and elevate the technical bar of the team. Expect to be evaluated on your communication style, your ability to work cross-functionally with product and clinical teams, and your adaptability in a remote-first, fast-paced environment.

4. Interview Process Overview

The interview process at Cohere is designed to be rigorous yet practical, often moving relatively quickly compared to industry giants. It typically begins with a recruiter screen to align on your background and interest in the healthcare space. Following this, you will likely engage in a technical screening step.

A defining characteristic of the Cohere process is the emphasis on practical assessment, often in the form of a Take-Home Assessment. This assignment is critical; it is not just a pass/fail filter but a conversation piece for subsequent rounds. Candidates who advance past the assessment move to a series of virtual onsite interviews involving the Hiring Manager, peer engineers, and potentially senior leadership or a cofounder, depending on the role's seniority. The focus throughout is on your ability to deliver high-quality work and your fit within an autonomous, agile culture.

This timeline illustrates the typical flow from application to final decision. Note that the Technical Assessment stage is a significant hurdle where many candidates are filtered out. You should plan to dedicate uninterrupted time to this stage, as the quality of your submission directly dictates whether you move forward to the onsite rounds.

5. Deep Dive into Evaluation Areas

Your evaluation will center on your ability to execute tasks that mirror the actual day-to-day work at Cohere. The interviewers are looking for signals that you can handle the complexity of healthcare data integrations and platform engineering.

Coding & Practical Assessment

The technical assessment is the most critical pivot point in the process. It often involves a realistic problem statement related to data processing, API development, or system integration.

Be ready to go over:

• Code Structure: Organizing your project logically with clear separation of concerns.
• Testing: Including comprehensive unit and integration tests; submitting code without tests is a major red flag.
• Documentation: Writing a clear README that explains how to run your code and the trade-offs you made.
• Error Handling: robustly managing edge cases and failures, which is vital in healthcare applications.

Example scenarios:

• "Build a service that ingests data from a third-party API, transforms it according to a specific schema, and exposes it via a REST endpoint."
• "Refactor a piece of legacy code to improve its performance and testability."

System Design & Architecture

For Senior and Staff roles, you will face design discussions focusing on scalability and reliability. You need to show you can build systems that don't just work today but scale for the future.

Be ready to go over:

• Data Modeling: Designing schemas that support complex clinical data relationships.
• Integration Patterns: Discussing synchronous vs. asynchronous communication, message queues, and event-driven architectures.
• Security: Implementing authentication, authorization, and data encryption standards suitable for healthcare.

Example scenarios:

• "Design a prior authorization system that handles high concurrency while ensuring zero data loss."
• "How would you architect a platform component to be reusable across multiple different payer integrations?"

Behavioral & Leadership

Cohere places high value on autonomy and ownership. Interviews with Hiring Managers and Team Leads will dig into your past experiences to predict future behavior.

Be ready to go over:

• Conflict Resolution: How you handle disagreements on technical direction.
• Mentorship: Specific examples of how you have helped junior engineers grow.
• Ambiguity: Times you delivered a project with unclear requirements.
