Quad Human Resources Manager interview questions

They used a recruiting company and recruited me. Process took over 2 months to get to interview. Interview was with 5 different people and took over 4 hours. The actual Quad recruiter (the last interview) was harsh and asked all the same questions previously answered, she was condescending and rude. The external company told me I was an excellent candidate, one of the top three for the position and called me on a Saturday to tell me. I NEVER heard from anyone again. Not a form email, not a phone call, text, ABSOLUTELY NOTHING. 5 months later, I moved on and reached out the recruiter to see if I could get feedback, said absolutely will call me back. NOTHING. So UNPROFESSIONAL. I didn't even get a canned email. 1 year later I saw the position open on a job board, laughing I absolutely know why. 2 months of phone calls, emails and finally a 4 hour long interview for nothing. Believe me I did not apply when I saw the job open.
