When people use "minimum" or "maximum" and then follow that with a range.
I once applied for a job where one of the requirements was "minimum 5 to 10 years experience in X". My friend told me to submit a CV saying I have 3 to 6 years experience in X and see if they shortlist me.
This comment is very dumb and frankly quite rude. The company is defining the requirements for the application themselves - so they have no reason to reflect scientific uncertainty or whatever you're getting at in their ad.
If a candidate is smart, I'm willing to accept less experience. If a candidate is less smart, I want them to have more experience. There is uncertainty in the minimum experience I'm willing to accept.
While there are certainly cases where this annoys me (as another poster pointed out "up to 60% or more!"), this is not one of them as it could have an explanation.
