Well it will be pled down to misdemeanor and juvenile record will be sealed, but yeah that pretty much ruins job applications.
Even an American adult, in most states, can make a felony disappear with some effort and the cooperation of the convicting judge. In other states, it becomes a charge but no conviction is recorded from the company's perspective, so you can say "no, I've never been convicted of a felony."
(I'm a felon with extensive experience in this area.)
Typical BigCos get a standard background on you (these are measured in dozens of dollars), and any further investigation that involves a human being is reserved for a very, very rare candidate. HR and operations are expensive at scale.
Since everybody rational considers this news item ridiculous, I think we can safely say this girl will be alright. The expulsion is the thing she'll have to work around, but even a felony conviction is not a life-ender. Many companies specifically hire felons because they're a tax break if filed properly.
Entirely false.
I can't be the only one here to have passed this process. I've done it a couple times. This vaguely resembles my military security clearance some decades ago in that my Army CO never had any idea I got picked up by the cops for truancy after skipping out of gym class in my sophomore high school year, but the clearance guy knew, didn't really care (I mean, come on, really?), and issued my clearance and that credential is good enough for my CO not to personally investigate my police record.
Needless to say the pass fail criteria provided to the 3rd party doesn't include things like "Is the candidate a jew?". They ARE often dumb, but not that dumb.
Usually it involves a lot of verification of resume "facts" like if the candidate claims no criminal record but a simple glance at a public facebook feed shows all manner of talk about his extensive time in jail, the red flag gets raised. No need to tell the company what church he attends, just warn them to take a second (first?) look at the criminal background report.
There wasn't a news article about me so I don't have to worry about being Googled. I do feel bad for the girl because of that. However, so far employers have found my story amusing so I'm convinced that high school hijinks affect job prospects terribly.
