Human Dynamic Business Development Manager interview questions

Interview taken by 2 junior employees who seemed as if were taking an interview for the first time. The questions asked were too basic and can't possibly help in guaging anybody's competence. As a next step was asked to prepare the company's presentation, which is not the job of a BDM. Also, what was the purpose? It's not possible that a 30 year old MNC did not have a presentation. Was getting screened for both part time or full time options. Not shortlisted for either, request for feedback ignored. Still not sure what the selection criteria was.
