Difficult to say. I have interviewed lots of people over the years, and have noticed that many people in charge of the interviews barely read the CV in advance.

If you were already invited to an interview, a good interviewer should make most of his impression from you yourself and your answers, and less from the CV. From the applicants side, these days it is common for people to put lots of buzzwords... and when you ask many times you discover that they know not many more than the buzzword name.

So a good interviewer should make a lot from the interview and not from the CV. But then, a lot of other things come into play: Yours and his attitude that day, your 'chemistry', etc. Passing an interview is tough and it is recommended to go as much as you can, since practices makes perfect.
