If everything is over (conditions completed, deferred charges dismissed), then I don't think there's any advantage in waiting. If they're going to turn you down, they're going to turn you down, but as mentioned I can't imagine this is a big deal. You'll fully explain what happened during the crime and what happened during trial. They may ask for the court records to make sure you're giving them the straight story.

Most job applications (for good reason) only ask about convictions. You can truthfully answer you were not convicted.
