My brother was offered a promotion in his current department to perform the same job he's been performing for years. Instead of just giving him HIS promotion – he has to jump through hoops.
First they had to post his promotion/new job internally AND externally. Meaning coworkers are pinging him and asking if they'd be good fits for the role…
Then he had to have a phone call with a recruiter. Now he has to interview with the team he's already working with every day…. for his own PROMOTION.
If his boss wasn't constantly letting him know it's his position – why wouldnt he think he could lose it to a random applicant or internal applicant.
This is one of the reasons you interview for jobs and never hear back. What an ENORMOUS amount of wasted time and effort on the recruiters, HR, management, applicants (internal and external), and for the person a position already belongs to.
