"I can't say that I'm the best person for the job, because I haven't met and won't meet the other applicants. I can tell you why I think I'm qualified, if that would be helpful."
Honestly, I think my experience speaks for itself,
I'm a real go-getter, a self-starter and I work well with others. I value efficiency and productivity.
I have the drive and energy that others don't, when 5pm rolls around and everyone else leaves, I stay and keep working g until i feel i have completed my set goals.
My functional and domain skills that I have gained over the period, the process skills to show my discipline, the interpersonal skills that keep my team momentum going and the technical skills that I could contribute to the project success.
