If reality worked the way hiring managers and job interviews thought it did companies would have to fire everyone when they purchased new software since no one would have any experience using it.
No idea about privilege, but when I was struggling to find a job, that was a lesson I learned as well. Instead of applying only to 100% fit which is what I was doing, I started applying to the 50% and everything in between. This increased my chances of talking to someone at least, but also increased the amount of work I had to put in applying to everything. But just like in sales, after you get that first call, the chances of getting somewhere are much higher, so some things have to get flexible to make it happen.
