Default some fields in Candidates from Career centre

Summary:

Is there a way to default some information for candidates, example , instead of asking for state or country in our career centre, is there a way to automatically populate it to a specific state once it creates a candidate record? We also want to have automatic tags or identifier to candidates based for example on groupings (e.g Graduates). when their candidate record is created from career centre, is there a way that their candidate record be tagged with such identifier?
