As an ex-con, these kind of attitudes really concern me! Hoping when I graduate university I can find a job somewhere that will be willing to overlook my teenage years.
Background checks are not perfect, we know. That's why when you apply, you have the right to get a full report for free. I always recommend checking that box to get it when applying. That way, if something comes up, you can dispute it with the background check agency, and it's very easy.
