In the usual sequence of events/at the appropriate time.
I don't think it means low priority, though, just that you've not got a fixed time. You could be triaged at A&E and told you'll be seen in due course; you could be interviewing candidates and tell them they'll be informed if they were successful in due course. It won't mean you're not bothered, only that you're doing things in the proper order and you don't yet know how long it'll all take.
