Sort the applicants (ether randomly or by criteria of your choice) and hire the first one who meets the minimum qualifications.
You don’t run it for everyone, just people who seem good enough and are willing to do it. A resume filter and a 30-minute conversation are usually enough.
You stop as soon as you’ve got your hire. If you’re bad at picking people for the screen, you learn the signals quickly because of your level of investment.
It does replace a longer traditional interview loop. You hardly talk to them up front. You tell the candidate you will extend an offer right after the work phase.
Another objection is not everyone can afford to spend that time with you. That’s true. We would pay them, and still got some refusals. You have to accept that every interview style works better for some candidates than others. You’ll also find candidates who love it.
I'll talk to recruiters and interview at other companies on my spare time, as before.
The false negatives suck for both candidate and hiring company who have accidentally rejected someone they would have like to have hired.
The benefit of the "provisional employment" process would be that even if it doesn't help avoid the false negatives, it would weed out the false positives so that the company at least ends up hiring people who are qualified and a good fit (even though due to the false negatives they may have rejected even better candidates).
Given how arbitrary in terms of talent mass layoffs are, there are of course tons of highly qualified out-of-work candidates (and due to age discrimination, maybe some of the best/most-experienced ones!), so this certainly might work to draw from that pool of candidates.
30/60/90 is pretty standard stuff. It’s literally the documentation and justification you need to fire the employee at the 90 day mark if you need to. Like a preemptive PIP if you will.
I don’t want to hire anyone who doesn’t want to be held accountable to what they say they can do anyway.
In the US at least, firing people for cause is difficult to do. More likely you just wait for next RIF and include your low-performers on the list.
So, yes, this is business as usual to some extent, but it's not a very cost effective or efficient way of hiring. If you really have work that needs doing, then you want to hire someone able to do it, not have a haphazard hiring process where it's a crapshoot and "if they don't work out we'll just fire them in our annual RIF, and try again".
