Did I do bad in this hospital admin interview?

Hi!

I recently got an interview after 6/7 months of trying to apply to various jobs. The interview was generally fine (minus them thinking my previous work experience was a job and not volunteer) and I noticed the interviewer smiling/nodding a lot. They then asked me one specific job question and I did not have as much experience in it and I feel like that may have caused a change in their judgement.

They did say they would get back to me by the end of the week, but did not ask for my references. Is it a sign that the interview did go bad then?

I know I can not definitely know but maybe others with similar experiences with hospital admin interviews could chime in?
