NiCE Sales Engineer interview questions

I was scheduled for an initial screening with a senior talent acquisition manager who informed me that he would not be able to make it and asked to reschedule 5 minutes into the meeting start time, which is fine. However, when I went to follow up, he blocked all incoming emails from my IP. I tried to message him on LinkedIn and no response, go figure. Nice doesn't have the best reputation in the market, so this shouldn't have been a surprise...beware.
