Hiring managers receive dozens - sometimes hundreds - of résumés for any given opening.
They don't have the time or resources to review each one closely, so they spend approximately six seconds on their initial "fit/no fit" decision.
You may be perfect for the job, but if your résumé has just one typo, if it's formatted poorly, or you use the wrong font, it could easily end up in the "no" pile.
