I can honestly say that I have never in over 25 years gotten a job based on blindly submitting my resume. My first paid development gig in 1990 was based on someone at another college reaching out to me based on some Mac shareware they found on the ftp Info Mac archives (yeah I’m that old).
My first job was based on an internship I had the year before from bugging the career center at college.
Every subsequent job has been based on either former coworkers recommendations or working with local external recruiters.
