Medallia Front-End Engineer interview questions

I was contacted by the recruiter the day that I submitted my resume. The recruiter asked me for a convenient time to talk. I replied about 15 minutes after receiving that email and I suggested the following day in a 2 hour window to allow her to select a time that was convenient for her. I didn't hear back from her until 24 hours later saying "I didn't see your e-mail and my schedule is too packed today". Red flag. I replied that it wasn't a problem and asked her to select a time that works best as the next day as my schedule was very flexible. She suggested the following morning at 9:00 AM to which I let her know that would be perfect. I spent the night prepping and researching the ins-and-outs of the company. I woke up 2 hours early that morning to get a little extra time in as I was very excited. 9:00 AM hits. No call. 40 minutes later I receive an e-mail saying "Meeting ran long - let's reschedule". No sincere apology. No concern that I sat there for 40 minutes waiting for her to call. I replied back a few minutes after receiving that email that I had set aside about an hour for our conversation so I would still be available to talk if it was convenient for her. It's been 48 hours and I haven't even received a response. This is the first line on Medallia's summary: "Think about the last interaction you had with a company. Was it a good one? Could it have been better? These questions sound obvious, but not to businesses. Most organizations don't know whether your experience with them was good or bad — and how they could improve it in the future. Medallia’s cloud-based platform solves this." I was so put off by the lack of respect for my time and schedule that I didn't bother rescheduling the phone screen which was disappointing because I was extremely excited about this opportunity.
