If I was convicted of a misdemeanor 1 for theft but it was expunged 4 years ago, but my job will do I background check, will it still be on my record?

I've never been charge with anything again. Not even a traffic ticket. I'm getting a job at a bank and they need my fingerprints and I was wondering if they will still show my arrest. I've never had my fingerprints taken since the expungement but I've passed 2 background checks. Just want to know if I should be worried.
