Delta Capita interview questions

One interview only. They test mostly your knowledge so they can see if you can do the job but they of course throw in some behavioral questions here and there

I applied for the role and completed multiple stages of the interview process. After being asked to confirm availability for a subsequent stage, communication stopped and no further updates were provided. Several months later, the position is still being advertised. Completely unprofessional and I am led to believe the job was never real to begin with. A waste of time and frustrating to deal with.
