As the title says 
It is internal promotion, it is the only promotion opportunity that will ever come up in the organization for me but the manager has told me the competition is extremely strong and includes much more senior people than this position is.
I have a strong suspicion that she forgot to shortlist me (even though she told me I would be shortlisted) and my interview has been crow barred into the interview date. Clearly the interview is just lip service because I am internal and have always been viewed as the natural successor to this role from within the organization - however it was advertised externally hence the competition.
I face a week of stress, homework etc for what appears to be a futile task - what do I do?,
