Meta Program Manager interview questions

Met with the recruiter first then the hiring manager. That went very well and the hiring manager confirmed they would put me through the interview loop which is to meet with 5 interviewers for 45 minutes each. A few weeks after the interview and not hearing anything back I emailed the recruiter, who replied back the following week asking my availability the next two days. After I replied back I never heard back, after all the time and effort I put into the interviews.
