That wouldn't work. Candidates would just create multiple accounts, and apply from multiple job boards. Or they would use the job board to find the employer's own careers web page and apply directly there.

Apps like tinder already deal with the multiple account problem - not an unknown challenge.

I’ll admit the second issue is harder, and would require some kind of common application standard framework.

I still maintain that the status quo of noise drowning out signal is horrifically bad, and I don’t think job boards making things even more frictionless is helping.
