Motorola Solutions Internship interview questions

Unprofessionally texted about an interview out of nowhere. Interviewer asked fair questions for the role. C++, python questions. Interviewer was outwardly rude about the worth of my current experiences and projects. Asked about a serious research project I am involved in, and after explaining its significance for the field they essentially laughed at it as if it were not serious at all. Very unprofessional.
