Interview process

1. Online application.
2. HR phone screen.
3. Technical phone interview with the manager, including a system-design question.
4. Take-home coding assessment.
5. Virtual onsite planned as the next stage.

The recruiter scheduled interviews quickly and communicated consistently. The candidate reached the fourth step and was rejected after submitting the take-home assessment, so the planned virtual onsite did not take place.

Reported system-design question

Design an end-to-end system that manages and automatically executes user scripts.

The report does not disclose supported languages, triggers, scheduling, isolation, security boundaries, quotas, retries, logs, artifacts, APIs, scale, latency, or follow-up questions.

The corresponding FastPrep exercise is Design a Managed User-Script Execution Platform. Its complete execution and isolation model supplies a bounded practice scenario without treating those authored requirements as details from the interview.
