Interview Prompt
We measure TV viewership for every major network and streaming service in the US. We collect second-by-second viewing data from a 40,000-household panel and set-top box data from 45 million devices, and our clients - the networks, advertisers, and agencies - depend on our overnight ratings reports. Design a pipeline that processes this data, applies the panel weighting to project national estimates, and reliably delivers reports to clients by 10am every morning.
