Had a job interview, which in all honesty was surprised to have got. I did a lot of research, asking friends that work in a similar role, visiting the place, my own experience and practised the questions, scenarios etc. Found out today that I didn't get the job, the feedback was I needed to research the job description...me and my husband went through the job description and person spec with a fine tooth comb. When I asked if I could have a little more detail I was told to expand my answers and research the job description 
I just feel like what was the point of offering me an interview if I needed to research the job description? They wrote down loads in my interview and I thought it had gone well.
It's a job I haven't done before but my current job has plenty of transferable skills and I could do the job standing on my head. I honestly can't think of what I've said to get such terrible feedback.
