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. 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.

3. 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.
