of the interview process to ascertain your suitability as a data scientist hire.
In interview scenarios, the common kind of ‘test’ comes in the form of (i) asking you to comment on an
existing/given visualisation or (ii) asking you to walk them through the process of graphing a small data
set. The aim is to ensure that you not only understand analytics but also the art of communicating that to
stakeholders effectively.
