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.
“Minimum” in this could refer not to the number of years but to the criteria of eligibility. The sentence might mean “At minimum you have to pass the following eligibility criteria: between 5 and 10 years experience.”
If they then give other criteria that you have to match, that’s nonsense :)
Or I suppose it could mean they’re looking for someone with a minimum of five years, and while they’re not looking for someone with more than 10 years they will consider them. “We want someone with (hard minimum of 5) to (soft maximum of 10) years experience.
Is the job for someone to improve the clarity of their communications by any chance?
Your first interpretation wasn’t the case in this specific ad, because the “minimum 5-10 year experience” was on the list of “essential experience and skills” and there was a separate list of “desirables”.
Your second explanation just supports my original infuriation - just state the range that you’re interested in, without calling it a minimum.
Actually, I got that job, I’m still working for the company, but to your last point, I have to say it’s hilarious how bad our communications dept is at communicating to the rest of the company.
