I attended an interview on Monday and the person who was heading the panel said candidates would be contacted on Wednesday, after a panel meeting on Tuesday. (I privately thought the successful candidate might be contacted later on Tuesday, so then other people could be informed the day after.)
Both Tuesday and Wednesday have come and gone. I think the employer, a large organisation which gets public funds, wouldn't be the sort of place that just left people dangling in uncertainty.
I'm assuming now that I'm very unlikely to be their first choice. But if you were me, and still hadn't heard anything by this coming Monday, might you contact the HR people, for confirmation?
