WorkWave interview questions

This was genuinely the most unprofessional interview process I have ever experienced. The recruiter never responds to emails. I went through 4 different interviews, just to be ghosted by everyone at the company. I followed up to multiple people via email and even LinkedIn and received no response even though I was told I’d hear back by a certain date. I did a mock sale, met with VP of Sales, everything… no response. Extremely unprofessional in my opinion to interview someone through 4 rounds, see they are trying actively to get some answer on the status of the role, and just ignore them.
