I was overly broad with that, excuse me. It's much more complicated, but generally you can't exclude someone based on a criminal record alone as you rightly point out, and that's not accounting for other circumstances. So yes, financial will matter (of course, any financial crime means that license will be revoked and that record will be accessible as well), but unrelated crimes are different.
The main reason someone gets rejected from criminal reasons, in my experience, is having an old record that's been cleared or expunged, and then answering "No" when the employment application asks a specific wording of "Have you ever been convicted of a crime?" - The answer would be yes, and a criminal check would reflect something had happened, but that the record has been expunged due to enough time passing for that particular crime. It sounds convoluted, and it is. Not sure it really should, but I only worked in the industry. Whether or not the industry followed the letter of the law is much, much different.
