Complain of Bad Management by Consultant of the Store

Good day

Please assist I'm find this very strange, disappointing and very poor, this McDonald's Dobsonville Point had vacant for Crew Trainer whereby few employee app**** for that post but only one was called for an interview( Was that an interview or was that position reserved for that person) and played with other employees to apply just to fool everyone. What I don't understand is why was the position advertised from the beginning?, Is this fair to other employees whom app**** for that position?, Isn't all of them were supposed to be called for an interview and let best come right other than one person?, Was this consultant who interviewed that person to the other by not calling them or she a biased, ****** or have favourism, this to its pure ******** and please I need this consultant to be dealt with ASAP and recall everyone app**** for this vacant to be interviewed or the deal company deal her unfairly treatment. This is unacceptable., can she be exposed for this bad management of that store.
