Ben G. - "Situation - A time I had to think “outside of the box” was while I was at Google working on hotel solutions for smart displays.

Manish G. - "When the COVID influx started to flow through hospitals, there were a lot of questions and no time to find solutions. So we set up a command center to manage the flow of issues, triaged them appropriately, and mobilized teams to find quick resolutions. We had to escalate quickly and effectively to find quick resolutions. The team had to rotate the leadership of the command center to avoid burnout due to working round the clock and in unconventional ways to manage the workload. For example, we ha"See full answer

Anastasiia V. - "First, I would operationalize the term "slip" by asking: What’s slipping — delivery, scope, quality, or decision-making?

Clayton P. - "I've watched all the ML Systems designs interviews and this solution provides a clean baseline for predicting ETA using historical averages, but it falls short of addressing the broader problem of route planning. The system predicts ETA for a given segment and time interval, but it doesn’t explain how to compute the ETA for an entire route or how to integrate this into dynamic path selection. It also lacks depth on handling real-time data, adapting to distribution shift, or reacting to sudden"See full answer
