Sample interview questions

How would you design an A/B test for an upgrade prompt in a SaaS product?

I would begin with a clear hypothesis, such as whether contextual messaging at a feature limit increases upgrades. I would define the eligible audience, a control and treatment, primary metrics such as completed purchases, and guardrail metrics such as support contacts or churn. Before launch, I would validate instrumentation, decide the required sample size and stopping criteria, then document results and the recommended follow-up.

Describe how you would implement a full-stack feature in Ruby on Rails and Vue.js.

I would clarify the user flow, acceptance criteria, data model, API contract, and success metrics first. On the backend, I would implement the Rails model, service or controller logic, authorization, tests, and observability. On the frontend, I would build a Vue component with clear loading and error states, integrate it with the API, add component or end-to-end coverage, and monitor the feature after release.

What steps would you take if an experiment produced an unexpected drop in conversion?

I would first verify event tracking, assignment logic, and data quality to rule out measurement errors. If the decline is credible and exceeds agreed guardrails, I would stop or roll back the treatment promptly. I would then investigate segment behavior, performance regressions, usability issues, and implementation differences before documenting the learning and proposing a safer iteration.

How do you keep a Rails application performant when working with relational data?

I would inspect query patterns, use indexes that support common filters and joins, avoid N+1 queries through eager loading, and paginate large result sets. I would use profiling and production monitoring to identify real bottlenecks, then consider caching or background processing where appropriate. Performance changes should be measured and covered with tests so they do not compromise correctness.

How do you communicate progress and technical decisions in an asynchronous team?

I write concise updates that state the goal, current status, decisions needed, risks, and next steps. For technical decisions, I document alternatives, trade-offs, the chosen approach, and links to relevant issues or merge requests. This creates an accessible record, lets teammates contribute across time zones, and reduces reliance on synchronous meetings.

Improving the tooling the team uses to run and read out experiments

What you’ll do

Design, build, and iterate on A/B tests and experiments that increase first purchases on GitLab.com and self-managed GitLab.
Build and improve registration, trial, onboarding, and in-product upgrade and purchase experiences to increase completion of these steps.
Implement backend features and services in Ruby on Rails and frontend experiences using Vue.js.
Analyze experiment results and product usage data with Data Analysts to decide which changes to keep, iterate on, or roll back based on first-purchase outcomes.
Collaborate with Product Managers and UX Designers to define hypotheses and success metrics before shipping experiments, then compare results against those metrics.
Maintain and improve our experimentation framework and tooling to increase experiment throughput and reduce the time from setup to results.
Collaborate with other Engineering teams, including Fulfillment, to remove purchase barriers across GitLab’s codebase.
Document decisions, review code, and share experiment results asynchronously so distributed teammates can track shipped changes and their measured outcomes.

Experience working with relational databases and a solid understanding of web performance optimization.
A track record of shipping features to production and owning them after release.
Ability to use product data to decide what to build, keep, or roll back.
Ability to document decisions and share updates asynchronously with distributed Product Management, UX, and Data teammates.
Ability to organize your work, seek and apply feedback, and collaborate inclusively with teammates from diverse backgrounds, in line with GitLab’s values.
