What's Mallard raving about today?
As someone who regularly interviews and hires people, I can tell you that the way people dress to interviews is a reliable economic indicator. When times are bad and competition is fierce, people dress up for interviews. When times are good and qualified applicants are scarce, people show up dressed however they like.
They do this because they are rational human beings and most sane hiring managers assess the applicant more than their dress, absent corporate culture like IBM where failure to dress appropriately is an accurate marker for someone who won't fit the culture.
Mallard, by contrast, is an idiot who knows nothing about doing actual work for a living.
