I was completely ghosted after being requested to prepare a very long tasks which included a whole presentation and a sales analysis. My interview was cancel a couple of days before it was scheduled and then was told they were finalising internal movements and had to wait before rescheduling the interview. I have never heard from anyone since, and it's now been about 3 months since the whole process started. This is a complete lack of respect as job hunting is not a joke and requiring to invest time in completing long tasks to be then ghosted is unprofessional and rude. At least an email saying the role has been filled internally and apologising would be appreciated.
