If you equate "be ambitious" with lying, that says more about you than it says about resumes or HR.
Ambition is what you can become, not what you are.
The only way of applying without dishonesty would be to do so while openly saying “I don’t tick all your boxes, but I still think I’d be a good fit because XYZ”. I might like this if I saw it in a job application, because it means the applicant was paying attention and not just applying to everything… but that doesn’t work so well when there’s already a “Preferred Qualifications” section, and might even have the opposite effect.
If a job says you need 8 years of experience and you say you have 8 when you have 4, that is lying. If you apply to a job that says you need 8 years of experience and you only have 4, that isn't lying. It isn't dishonest. It would be like the person selling that PC asking, "hey, might 4GB work if we throw in a better processor?"
Is "doesn't want to waste our time when we tell them not to waste our time" really an important attribute for you to reject candidates on? Or would more accurate "minimum" requirements be better?
That's exactly what I meant by being ambitious. I think you shouldn't lie when applying for a job, but on the other hand there is a shortage of applicants in tech. You could recognize this as an opportunity if you're confident that you can "grow to the desired level" of the job offer.
But what is a candidate to do? Skip the job, because they don't have the required qualifications? Assume the requirements aren't real? Dress up the resume with some fake barely there qualifications to fit?
Different cultural backgrounds will have different responses, and very few will really be lying.
The worst thing, though? The knee-jerk response to the ones that dress up the resume is often to want to add even more requirements...
