Because companies rely on asymmetric information to their advantage. It’s why they allow a culture of not discussing pay and wages, because if you knew that your peer is getting paid more than you with less experience and time in the company, you would either demand more pay or benefits, or you will go someplace else. All companies are complicit in this.
The job I'm currently interviewing candidates for has 1800 applicants. I don't want a thread where that many people are talking, answering questions, and trying to get my attention for the job. I want a quick way to work through all the resumes so I can hire the best person.
A friend's boss used to take half the stack of resumes and just throw them in the trash. Why? "I don't work with unlucky people"
Resumes are generally a really poor way to find people anyway. I interviewed someone today who was great for the job but with a crap resume. What can ya do..
