Mr. Realtor seems to be a nice guy. But can we believe everything he says? After all, a realtor makes money from the sold price. So the higher the sold price, the better for him! Can big data be an unbiased source for price estimation?
How many times have we lost rising talents to competitors? It feels sad when they come back with a better package that we could not beat. If we had known when they were likely to quit, we would have given a larger bonus to prevent a job hunting attempt and could have kept talents with us longer. Data can do just that! 😀
