[arithmetic]

Great advice - I like the fact that Aaron keeps it real simple. I also like how he doesn't like questions along the lines of "counting the number of piano tuners in Chicago". I've been witness to interviews with similar questions and I'm always left wondering as to what the point was.

That said, I'm not sure if all of his advice can be followed by a reasonably medium sized company/organization where hiring decisions are made by a committee, rather than one person.

As a side note, I think that reading a resume can actually be a good starting point to understand the candidate's background.
