So I posted earlier about an interview, which I went to, but it turns out that the posting had mistakenly been put under the wrong reference so the job I've prepared for for the last fortnight wasn't the job I was interviewing for.
It wasn't even marginally different, it was a totally different job and not something I would have originally applied for, despite being able to answer the questions with examples and tailoring my responses to their questions.
But I feel really deflated. I've got home and I feel like the last fortnight has been such a waste of time with all my prep and research. Aibu to be fairly cheesed off?
