Evangelical Hospital interview questions

The recruiter asked me the availability and expected salary via phone (which I stated on CV already). Then, she invited me to have a face-to-face interview the following day. I arrived 15 mins earlier on the interview date. The recruiter checked whether the original copies and the photocopies are the same. After that, she asked me to wait for the interview. However, they kept me waiting for 35 mins… It is disrespectful and unprofessional! There were 2 interviewers. One of them was so rude and impolite. She claimed that my expected salary was unrealistic. I was wonder why you invited me for the interview??? The recruiter knew my expected salary before inviting me for the interview. I supposed your budget shall be aligned with my expected salary. If you thought that my expected salary is not reasonable, you should not invite me for interview. You were wasting my time… Also, that interviewer kept interrupting me while I was answering her questions. It was the worst interview experience!!
