That is definitely a problem. Not only is it a human resources capacity, but it's a capacity to do what has been now downloaded to that particular manager. They just don't have the capacity to be able to do hiring processes in a fair and equitable manner. It comes down to, basically, training. They're not trained to hire people. They were trained to do this job, whatever this job may be, but it wasn't to hire people. Now you're asking them to hire people. They're going to ask the wrong questions. They're going to ask questions that only certain people will have the answer to, and that's certainly demonstrative of favouritism as well.
