FOCUS ON THE HIRING TRIFECTA
Principle #4 was to "Hire is to Predict"...
So what is it you're predicting?
You're predicting what I call "The Hiring Trifecta."
All bad hires come down to 1 of these 3 unmet outcomes:
1) PERFORMANCE - can they do the job.
2) RETENTION - can they stay in the job long enough to create value.
3) CULTURAL FIT - can they do/stay in the job without making everyone else around them miserable or less effective.
Because Every Job is Different (#3), the exact weighting you give to each of the above 3 outcomes during the screening process will vary.
If you're hiring a brain surgeon, you should weight performance more heavily.
If you're hiring a receptionist, you should weight retention/cultural fit more. After all, it's not brain surgery. :)
The point is you should be screening candidates for all 3 outcomes.
Most companies are pretty good at screening for 1, OK at screening for 2, but awful at screening for all 3.
