Employers now expect all CVs to be tailored to the job you are applying for, in a way one never did in the past and she rewrote her CV for every job application.
She also found that a lot of employers now had CV proformas. There is now so much pressure on them to treating everyone equally regardless, of age, gender, colour etc. These forms are often very structured. She also found that both CVs and interviews were looking for competencies and skills rather than experience, ie, what competencies and skills your experience had given you rather than just looking at experience.
