Data Interview Questions

This repository is a collection of the data interview questions from the mailing list run by InterviewQs. Slowly I will try and provide my answers for each of them - mostly as a self improvement exercise.

Note: the InterviewQs people currently charge $9 a month for the answers - which I don't subscribe to - therefore, the any answers in this repository are mine only and may or may not even be correct.

Note: The mailings do not always seem to make it to me, so where I don't have the data for the problem I will leave a marker, the intention being to fill the details in later if I manage to get hold of it.
