it is immensely frustrating to deal with automated systems, resume keyword matchers, no contact within a company and being ghosted after taking the time to write a proposal and cover letter that is a fit for the job description.
so what, he called an executive and got around their spam filter?
my advice
treat job hunting like a sales process.
you're successful based on the number of interviews you get.
figure out during the interview what's their decision making process.
read more books on sales and learn to handle rejection.
stop pursuing status jobs, at least until you have one with a good income.
