Yes, this is true that a recruiter rejects a resume in six seconds. There’s a good reason for it too. This is because those automated resume submission tools are wasting the HR’s time, and decreasing your chances of being selected.
In older days, you could read everyone’s resume. But, today this is not the case any longer. The automated services are firing off resumes and thus helping the recruiter’s save their time.
So, all you should do is to design your resume in such a way that it stands out in the crowd, thus meeting all the requirements of that particular field.
