A candidates view of self is not relevant.
If I offer you a job, I know your exact worth to my organization and your level of talent. My interview process leaves zero doubt about what you know, what you can do and how your personality will effect your capabilities.
Hahahahahha!!! No....you don't. I'd say you vastly, VASTLY....over-estimate the effectiveness of your vaunted "interview process".
I'm sorry, but it's virtually impossible to know someone that well after an hour long conversation, or even several hours. And even if you think you do, some people interview better than others, which has no bearing on their skill to do the job, unless you're paying them to be professional interviewers.
How about you give us weather report from up there on your high horse, boss?
