Reaching out to professor via email and was called for a project, expressed the interest. Later I was reached out b y one of the people working on the projects for an interview over the phone

No introduction, they asked me to start my interview presentation immediately. (5 to 10 minute PowerPoint presentation outlining background, motivations, research interests and future career goals.) I think the interviewer was quite rude, and was only invested in your technical skills and not your personality.
