Hi Veronica1, we didn't have to do in-flight announcements. virgin Australia has mostly prerecorded announcements and any other announcements are made either by the Captain/cabin supervisor, we had a one on one with the interviewer and then we did group activities.
AAA1, I'm currently in ground school and they told me that there are basically no more ground schools going for the next 6 months with virgin. That was from my LCC(leader cabin crew) who is in charge of all cabin crew for Perth.
