Does this have some implied conditions I'm missing? Because to me it seems absolutely obvious that filtering for people who have experience/a degree will vastly improve your outcome over true random hiring.
And, also personally, I've had great experience with people who migrated from absolutely unrelated fields (e.g. several people who retrained - within same company - from support into software development). Similarly I had great experience with fresh interns turning out to be brilliant theory people.
Are you saying that you had no qualifications at all before? Because that's what they're saying, just applying for any high-paying job, even if you don't have the requirements.
In both cases, I was switching industries (from ASIC design to IoT cloud software to data analytics). So, I arguably had some qualifications and arguably none at all.
