💡 Staff Software Engineering

The Staff Software Engineering Assessment is intended to be used as one of the first interview rounds to effectively capture signal on general core skills typically needed for a staff-level software engineer role.


At a high level, staff software engineers are technical experts, but also adept at collaborating with and leading others. The amount of code writing or decision-making a staff engineer is expected to do varies from role to role, but the questions in this assessment are designed to measure the quality of performance for these tasks.

Part 1 - Technical Roadmap and Systems Design (60 minutes)

A document writing exercise where candidates can edit and contribute to technical documentation. They can collaborate with teammates and demonstrate their ability to communicate via document comments.

Context and Question
Evaluation Criteria
Systems Design
Candidates will be asked to collaborate on the redesign of an existing technical system (connected to a roadmap) and provide recommendations on the systems performance and scalability.
Candidates are expected to address all the major fallbacks of the existing system and provide well-reasoned alternatives.
Navigating Business Requirements
Candidates will collaborate with stakeholders and optimize an 18-month technical roadmap while considering inputs such as the business goals, technical debt, process improvements, headcount, etc.
Candidates are expected to make difficult decisions based on technical and organizational constraints and will be measured by their ability to clearly explain their reasoning.

Part 2 - Code Review and Code Implementation (60 minutes)

A code editor exercise where candidates can edit and contribute to a complex multi-file code base and can provide technical feedback and guidance to teammates.

Evaluation Criteria
Code Review
Candidates will review a small, multi-file codebase authored by a junior engineer. They will be asked to comment on the quality of the work and provide feedback.
Candidates are expected to provide effective, targeted feedback that is actionable by their teammate and will be measured by the quality of their technical reasoning.
Writing Code
Candidates will work on a complex, open-ended coding task.
Candidates are expected to approach the problem given limited direction and complete this task by writing high-quality, compilable code that serves as a model to teach other junior engineers.
