Hey Donna,
No there won't be anymore interviews. The next step for you, I'm assuming, will be a medical, unless you've already done this.
You're really lucky though, as I was at a recruitment day on the 17th of April I think it was, and I haven't heard a single thing from them.
Who knows what's going on. Maybe they're sorting through Melbourne first? *shrug*
In other news, I cancelled my recruitment day with MAM today as I think I'd rather wait until I hear back from QCCA before going to another one. Here's hoping we hear something soon.
