No. No no no no no. Ask someone what their strengths are as a programmer. Don't ask them whether they are a good programmer.

Let's say I asked you: "Are you a good person?"

Well, compared to who? Compared to Mother Theresa? Probably not. But compared to the average person on the street? Probably.

If I asked you that question, I'd learn more about who you compared yourself to than whether you are a good person.

(Also, if I asked Mother Theresa that question, she'd probably have compared herself to Jesus and said 'No.')
