In the UK, it's changed recently because of a Supreme Court ruling, but AFAIK there are various levels of check depending on the specific job. In most cases a conviction for which the person was sentenced to less than 4 years in prison will eventually become 'spent' and won't show up on background checks apart from for specific jobs (such as working with children). Even for those jobs, some minor convictions are 'filtered' and removed from the record.
