I said we should clean it up. Try to see which variables we can get rid by checking for collinearity. The interviewer's followup question was - what about even before this? I said "determine the goal as in figure out what we want to accomplish". She then asked "how we do this?" We just kept going in a circle with this question...

I would say that we should visualize the data first, getting a sense of it. How many attributes it contains? What are the ranges of the attributes?

These are typically the first thing I'd like to know when investigating a data set that I have no previous knowledge of.
