Today, for your app to end up top-of-the heap:
1. Your need a separate resume for each job, with a customized job objective and summary.
1a. It must tell a story, using paragraphs if necessary, that make clear that you're a better problem solver in your niche than anyone else.
1b. So the employer's resume-selection software picks out your resume, it needs to include all the right keywords. Get them from the job ad you're responding to as well as to other similar ads, which you can usually find on indeed.com, simplyhired.com, or other job site containing ads for your kind of work.
2. If you can look natural and relaxed on camera, create a video resume, for example, at CareerBuilder, which offers dos and dont's, and it's free. Include the link to it in your text resume.
3. You need a cover letter that powerfully explains why you'd love to work for that employer.
4. Both resume and cover letter must avoid job-seeker jargon; for example, "self-starter," "team player," "delights in exceeding customer expectations," "uniquely qualified." Those sound like B.S. canned phrases that came from resume software or a resume writer. Also, those terms are distancing; you want to create connection.
