Interview Prompt
A 12-engineer SaaS startup is three weeks into building a 5-node analytics pipeline because the CEO asked one question last week: 'How many users signed up last quarter?' Nobody has asked since. Apply the section's four-question pipeline test on this scenario and replace the over-engineered scaffolding with one of the section's named simpler answers for a one-off question. The canvas should end with fewer nodes than it started.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write your pipeline design solution with real code execution
- Get instant feedback and a hire/no-hire decision
