They were very interested in chasing me for an interview, the Talent & Acquisition Manager asked what salary I would want and I told her and she said that should be ok, they have no set salary for the role. Had an interview with 2 people and it went well until they asked what salary I wanted. It is unusual for the person who you are taking over from to ask you this. Then they just ghosted me after a few emails asking what the situation was, either yes or no. I find them very unprofessional. A quick email letting me know would be the right thing to do.
