If I don't have some minimum requirements for candidates how would I be able to identify the right fit? I'm in an industry that lots of people want to be in. We get lots of applications. Some filtering must be done. The basic interview is one filter. The wrong candidate affects my company. That means it affects my employees too (most?). A critical part of the filter is to determine if applicant who WANTS to be here will fuck things up for the people I NEED to be here. Its not just about you.
