That describes someone I know down to a T. Bootcamp graduate, can barely code, but claims he's aced every interview and blames the graphic designers and business suits when he doesn't get an offer. He also expects to be paid like a senior with only 2 years of experience.

He has been fired from every coding job he's had, due to difficulties working with others. In a nutshell, he's convinced that he knows more than everyone else. (For example, he once spent 3 hours arguing with a guy who builds rocket systems at JPL about which of them knows more about rockets.)

Him and others like him have soured a lot of LA tech companies on hiring boot camp graduates.
