Tableau Software interview questions

The initial screening is an online accessment and after finishing it, I get the final virtual on-site. There are 4 rounds in total with 3 coding interviews and 1 behavior interview

Went through 5 interviews with the last being in front of a panel of four people with a presentation I had to create. I was advised during the panel interview that I would know the outcome within a couple of days. I followed up a week later as I had not heard anything and they said they were still taking others though the rounds and would get back to me. That was 4 weeks ago with no updates or contact. They also reposted the job ad two weeks ago. So they're either keeping me on the back burner or haven't bothered to tell me that I haven't been successful. You'd think that after 5 interviews and more than two months since the first, I'd at least be respected enough to be given a 'Thanks but no thanks' email. It speaks volumes about the Tableau culture.
