Applied Optoelectronics Industrial Engineer interview questions

They asked me to create a PowerPoint on my experience related to the role. The interviewer would interrupt mid slide and would tell me to go the next slide in a rude manner without even letting me finish or explaining why should I skip. Job description says they sponsor international students, but when I told him, he said he could just offer me a technician role since engineer roles were just given to masters and PhD graduates, which makes no sense because that was nowhere stated in the job description, and it was an entry level position. There were no specific questions, just him picking on the projects I have worked. Seemed like he was just trying to find out if I was lying or something like that,
