Dust Identity interview questions

Did research and applied online. Heard back a couple of weeks later and went through the first round interview with the internal HR person. Went well, asked if we would be moving forward and all things were in the positive. HR said how I'd be hearing back before the end of the week. That was a month ago. Nothing - crickets. Its not OK to ghost people or not have the common courtesy to communicate openly and honestly. This was for a senior level position of which I was qualified and had relevant experience. Pretty Mickey Mouse when it comes to follow up and follow through.

I had a total of four interviews 1) Head of Talent Acquistion, 2) SVP of Sales and Marketing 3) VP of Operations 4) Account executive. After four interviews it seemed extremely positive, and we were moving forward. I sent a follow up email and heard absolutely nothing back after a couple of attempts. They did not even have the courtesy to tell me they selected someone else which is fine. In my opinion that is a lack of integrity.
