Direct Travel interview questions

I had an interview scheduled with Sylvia, she never called when I emailed her she said she got tied up with another call, but she didn't let me know I had to contact her. Then she asked to reschedule another day at 10a I didn't hear from her again I had to send her another email she replied to say she was on a call, she finally called 11mns after. She didn't apologize the 1st thing she ask me is to tell her about myself. Seriously? Aren't they to starting tell you about the company ect? Employers need to respect Candidates. If it was the other way around I wouldn't even get the chance to reschedule.
