Resume writing: to “beat the bots” you need a human’s help

There are countless job listing sites on the internet. The most successful of these makes matching jobs with potential hires easy. Better still, most offer “1-click” tools so you can apply for a new position in just a few seconds. Then the waiting game begins. And unfortunately, you might never hear back from the company in many cases. The reason for the silence could be the organization's application tracking system (ATS). 

Many companies now use an ATS software app to automate hiring, improving efficiency and saving time and money. But, unfortunately,  an ATS, by design, uses built-in criteria to remove applicants it doesn't believe are qualified for an open position. In other words, you might have been removed from the pool of candidates without anyone seeing your resume.
