You can do that, but even in exactly the same market, two different companies (or contract firms, in my case) may want diametrically opposite changes to your resume (or CV, in your case). Here in the DC area, I was told to play down my business ownership and that the amount of money I was asking was "unrealistic" (and did I want to maybe talk about something 20-30K lower?) within a coupla weeks of being hired at more than the "unrealistic" salary by someplace I'd sent the older version of my resume. It's incredibly variable.

Unscrupulous recruiters have a habit of trying to get you to come down on salary. Remember that their incentives are not the same as yours.

I had the same experience. Had been employed at X, headhunter told me to consider jobs at X-15 (this was February 2007). I got one at X+35.

This could actually be better in some cases, because he can dress his deferred salary (which can be whatever he wants it to be with no contest, since it will never be paid) as an actual salary.
