You Know How to Use Macros in Excel?

I remember once in a job interview saying that I could use macros on Excel. So if people aren't familiar with these, in fact, I can't really explain. It's a really complicated thing on Microsoft Excel. The systems really changed actually. And the one I use at home is totally different to this. What version of Excel is this? If anyone needs someone to draw some stupid pictures in Microsoft Paint, look no further. I'm your man.
