A friend of mine was once interviewing an engineer for a programming job and asked him a typical interview question:
- How do you know when a function or method is too big?
- Well, said the candidate, I don't like any method to be bigger than my head.
- You mean you can't keep all the details in your head?
- No, I mean I put my head up against my monitor, and the code shouldn't be bigger than my head.
