Quest Software interview questions

The interview process was 4 rounds and moved fairly quickly. Your typical interview process with the expected questions. Recruiter>Hiring Manager>Peer>Director and took about 4 weeks to complete. 30-45 minutes per interview. Things went smoothly until they ghosted me after the 4th round. I emailed the recuiter a week after the final interview for feedback. She responded a week later that she would be meeting with the hiring manager the next day and would provide feedback then. No response after that. Ghosted.
