The interviewer was impatient, and instead of doing a self-/company introduction, he/she just asked me some questions about the job as process. He/she snickered at my answer about my personal plan, which made me feel very uncomfortable. Overall, the whole interview lasted less than ten minutes, I felt it was a very unprofessional interview, and the person/company had no interest in me at all, I don't understand why I was even invited for an interview.
