phone interview, onsite interview(five people will ask you questions)

The recruiter reached out to me to meet with the Hiring Manager. Totally 4 rounds with multiple teams including the chat with the hiring manager. The recruiting team kept me informed during the hiring process, however, once the hiring process was over there was absolutely no response. I don't blame the hiring team, but I expected a little courtesy from the recruiters to keep me informed having spent 8 weeks interviewing with them. Instead, they simply ghosted me in spite of me having written to the recruiter multiple times asking for feedback.
