Fuck off, dude. You have my CV, you have my Linkedin, you are going to take my interview then why the hell do I need to further include a “cover letter” just to tell you why am I a worthy fit for your esteemed corporation? Just to rub your ego? Nah, I'm not here for your entertainment. Either you put enough efforts in recruitment or you shut your corp down. These fuckers think we owe them something just for them existing.
