It does depend. Every school and organization is different.

When I went through informal the final time, one organization had a few scheduled events, and let those who were not being offered a bid know the evening that the final event ended by telephone call.

I'd also participated in informal for another organization at the same time. With them, I met two sisters for coffee and we chatted and enjoyed our drinks. I didn't hear about not being offered a bid until over a week later, after they'd held their pledge ceremony for those who chose to accept their bids. I believe that I received a call.
