Pentavalue interview questions

Almost my worst Job interview experience. The Interviewer who I thinks was the company owner seemed to be a college professor who was treating the employees like students at his class. She was mad that I didn't till her my current salary. And asked why didn't I have skills that were not mentioned in the Job post. She also asked about how often can I work at weekends and why can't I switch weekdays although it was written in the job post that workdays are Sunday to Thursday. Even HR girls were so unprofessional.
