Very good article, but I'm not sure if their advice for the answer to the salary question will always work:

>I’m not comfortable sharing my current salary. I would prefer to focus on the value I can add to this company rather than what I’m paid at my current job. I don’t have a specific number in mind for a desired salary, ...

Now what if they will offer you some salary, and you find it too low? You have just said that you didn't have a specific number in mind. To me it looks like that sentence threw away your opportunity to disagree with the offer and ask for a higher bid?
