Don't lose hope! I just called Zoe and she said that they're still sending out interview invites over the next few days She said to email her if you don't receive an invite over the next few days for more information on your application.
Hi Kat U., thank you for sharing this with us! Just to clarify, was "end of March" referring to interview invite dates or final decision dates? End of March invite dates seem quite late compared to previous years.
