My interview was amazing. The girl charged with doing it said she basically created her role which I found inspiring. Had an amazing interview and left feeling thrilled. Got a call the next day from someone who immediately identified themselves as "more senior than x" and said that she had to "pull [my] strengths and weaknesses out of x". Okay, that's fine. Little awkward to say it to me in that way, but fine.
She then read a note from the interviewer that said "seemed less than enthused about the on-call work". Which I found very unprofessional - not the note, but the fact that it was read to me.
The cherry on it was that despite the posting saying $18 to $22 an hour and money not having been discussed at any point during the interviewing process up until that point. I was simply advised that the role paid $18. It wasn't the money as much as it was the lack of context.
I felt like what was being implied by this approach was that the woman who interviewed me wasn't capable of making a sound decision on her own and that I needed to be grilled by x. That is just the sense I got, however.
Also, I recalled that the "more senior" person was senior by months. Not that that matters directly, but it made me walk away from the role and into one without these kinds of red flags.
