If you have a test that can identify a good candidate quickly then you have honestly struck gold and can genuinely use that to start your own company. I mean this with absolute sincerity.
One of the absolute hardest part of my business is really hiring qualified candidates, and it's really demoralizing and time consuming and unbelievably expensive. The best that I've managed to do is the same that pretty much every other business owner says... which is that I can usually (not always) filter out the bad candidates (along with some false negatives), and have some degree of luck in hiring good candidates (with some false positives).
Good candidates are not universally good, they are good for you after hire.
One of the best business analysts I worked with (also a profession, mind you) was almost fired when working under an old, grumpy and clearly underskilled one.
I was hired once without interview into a unicorn, was loved by colleagues but hated the work, the business and the industry, then left rather quickly.
See? There are mismatches and unknown unknowns, not just bad or good developers.
yup, the worst performance i did on any job was due to the complete unavailability of a manager when i was a team of one. and then that manager would not even fire me. i had to quit to get out of there.
Yeah sourcing developers / collaborating with developers is a huge barrier of entry. More than others factors such as deciding what software to produce for the market
