Pro Machinery & Equipment interview questions

Feeling uncomfortable throughout the whole interview process. When received a phone call to have an interview, I mentioned that I am not available to throughout the week and suggest interview post pone to the next week. The interviewer responded that may be they will find suitable person this week. If not yet, they will call back and confirm the interview with poor attitude. Finally, I had an interview opportunity next week and feeling uncomfortable. The interviewer seems don’t understand or misunderstand my opinion and explanations.
