Even if you are not selected, it’s already a success. Nothing to do with the Coué method: think about it this way, simply, you had an opportunity to improve your speech, so you’ll be better next time. And do not forget, that having an interview is already a success. For a single job offer, a recruiter can study up to 50, 60, 80 CV’s to select in the end less than ten. A success we tell you! Just stay positive!
