My goal is to not hire the bottom 50% of the workforce in a given discipline. IMO, you're better off building teams that make the average+ person more productive.
What's fun is that this isn't just a possibility, its likely! Despite the following being a clearly artificial argument, the general shape of it is true.
Let's say that you can rate employees 1-10 on each of technical skill and employability/soft-skills, and that both are equally sought by the market. Given how attractive your company is to work for and what you pay, its quite often true that you can allocate around 12 total points between the two categories. 13 point candidates have better offers from Google; 11 point candidates fail your interview process.
If you only hire people that strongly pass a strong technical interview, ensuring that their technical skill is at least an 8/10, then your employees will have at most 4/10 soft skills.
That of course works much better when everyone has their own office so the angry outbursts are only heard by the 2-3 closest neighbors.
Why most companies find it hard to find good sales engineers.
