i send 20 to 30 applications a day. i assume only 10% will respond. of which 1/3 i am underqualified, 1/3 i'm qualified but mismatch due to optics (biases) or culture or personality, 1/3 im the perfect fit.
it is all about the frame too, when you're tenured you are the buyer not the seller. you ask them what's their best offer based on your experience and their strict hiring budgets. you decide to say yes or no.
But I know that others have gotten an offer (or even several) after sending only a dozen or so, and so to them 10 applications might be "just enough". Some have even gotten new jobs multiple times without cold applying, where referrals are their way in and cold applying became history to them.
OP try 10 a week for six months and if you still can't find a job post here again (you won't).
some may be more qualified than you and thats a timing issue, also out of your control.
understanding the numbers game that the more you play the more chances of winning, that is something in your control.
