Interview Prompt
Our portfolio analytics platform shows clients their holdings value and gives the risk team intraday P&L that feeds NAV calculations, but positions only refresh in a nightly batch. Design a pipeline that keeps positions and P&L current throughout the trading day.
Summary
Positions shift by the second. The math cannot lag.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Draw your pipeline on the design canvas: sources, transforms, storage and checks
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
