Did a code test at an interview, had to aggregate data from a db. They stored cities with population count and users referenced cities.. 6 cities had a higher user count than population 🤔

They were a little taken back and suggested the population data must be outdated 😉.. it got a bit awkward

    Sloppy data, redundant data, incorrect data is a problem in lots of companies. Some big companies would be smart to appoint a Chief Data Officer to analyze data end-to-end. Often data is the most valuable corporate asset.
