Well, hackinthebochs never said that the assumption of competence was strong enough to prompt a job offer, you introduced that as a silly hyperbolic statement, so ridiculously grand in its claim - that 'an assumption of competence' can only be shown if it results in an instant job offer - that it appeared you were building a strawman with which to attack the idea that anyone had any kind of bias in favour of white males.

An assumption of competence doesn't imply that it will be allowed to stand untested in a high stakes scenario such as offering a job. However it will far too often stand untested in smaller scenarios, and it is exactly this assumption behind statements like "did you have your boyfriend help you with that assignment?" addressed to female students and not males, "you must be the graphic designer!" etc etc.
