Crossover for Work Customer Development Representative interview questions

I have an open process that is "under review" for over a month! Why advertise positions that are clearly not relevant or not actually open? It is extremely disrespectful to put candidates through 2, 3 hours o "real work" assignments and never even giving them a feedback. Or, what is even more bizarre, for the candidate to pass ALL assignments and not be selected for the process. Terrible experience! Don't even bother, it a complete waste of time!
