Goodwill interview questions

The job was put on hold after I applied. I was contacted a few months later for an interview. I was told to do a powerpoint presentation on how I was a good fit for the job-no other instructions on ppt requirements. The interview went pretty decent for the questions. They seemed to know nothing about the ppt. I let them know I had prepared it (using Canva and all the bells and whistles). They begrudgingly watched me deliver the presentation in total silence. It’s like they were mad or something. They asked what I was asked to prepare? How do they not know what their recruiting team is asking people to do? Then silence for weeks followed by a generic rejection. Horrible experience. They were rude.
