RAPP interview questions

One of the recruiters for RAPP reached out to me to apply for this position. I researched the company and applied on the company's website. I let the recruiter know I had applied and she then proceeded to schedule a day and time that would work for us both for our first phase, over-the-phone interview. On the day of the interview she never called. I reached out to her to let her know I was expecting to speak with her and about a week later she emailed me with an invite to reschedule and didn't mention why she hadn't called before. Cautiously I agreed, and I sent a calendar invite to her so we wouldn't experience a repeat of getting nowhere. She accepted the invitation and on the day of the interview, she didn't call again. I called the number I found in her email signature to try to reach her directly and left a voicemail on what I'm assuming was her cell phone. I haven't received a call back and at this stage, I'm no longer interested. Too bad for them.
