Docusign Senior Marketing Manager interview questions

I was referred by someone within the company, who mentioned that they were looking for someone with a specific set of skills and experience, which I happen to have. I was contacted by a recruiter within DocuSign, and then had a phone screen with her. Following this, I had an hour-long phone interview with the hiring manager and person who would be this role's manager. I felt it went well, and it seemed like a good fit on both sides. I then had two more hour-long phone interviews with other managers on the team (everyone was in a different city). Both of these I also felt went well, although one conversation was more in-depth and intense than the other. The recruiter then contacted me and told me next steps would be to have me come to California to meet senior leadership in person. Great. A couple weeks later, I hadn't heard anything so I emailed the recruiter to ask about an updated timeline and reiterating my interest. She told me she was touching base with the hiring manager that day and she would let me know later. She never did. I contacted her again about a week later to follow up, no response. Wouldn't even give me the courtesy of a quick email letting me know they were moving forward with other candidates. Very rude and unprofessional.
