They asked me to write an OO program to sort a table with 3 rows and 4 columns. Nobody in his right mind will do such a thing. Anyways, I wrote two classes, one for the data type and another for sorting. I figured they wanted to know if I knew OOP so I separated sorting from data, as it happens in every OOP lib or system on planet Earth. The 'unexpected question' was 'why did I you write two classes?' I explained I had two conceptually different things. They didn't get it.
