I don't think you got my point. My point is your CV forms part of the first impression that potential employers have of you. Even if he reads your CV while interviewing you, your CV will go on to influence his opinion of you. CV is not just to secure the first interview, it is a very powerful "impression" tool.

And you do agree that a well written and formatted CV is important for the right impression whether the employer read it before or during the interview. So I don't know what you are arguing about.
