Australian Centre for Education interview questions

For some background, I am CELTA certified and I have a Master’s degree in Linguistics. I applied to ACE IDP for an English teaching position (they claimed to have 30 vacancies in their advertisement), as did my friend, who also has a CELTA and a Master’s in English. After asking me when I was free for the interview, they sent my friend a Zoom link for the time I was supposed to have my interview. I reached out to them about this and received no response, but it was clear that they had confused the two of us. My friend’s interview went well, they said the mix up happened because they’re quite busy, and said my interview would be in 2 days. After this, they did not contact either of us. When 3 days went by, my friend reached out, and she received a rejection. I was simply ghosted- no response at all. I wonder if this is a normal occurrence or good old-fashioned lack of professionalism and discrimination (we’re non natives).
