Tameside Council interview questions

They took 4 months to invite me to an interview. I went and I found the interview panel to be nice and friendly and a good mix of questions. They told me they would be calling people with the outcome but ghosted me. Found a voicemail 4 weeks later saying hello just phoning to give you feedback. Tried to call back and the phone was off. Poor HR and recruitment process and really not fair to leave people in the dark like that. Really unprofessional.
