Hilton Front Desk Receptionist interview questions

It was simple and easy. I had 2 interviews and they both went extremely well. I was told to wait for an email in 2-3 days. It took 2 weeks and me emailing multiple times to reach back out. I received an email later that they filled the position with someone else who was certified in their system. They never mentioned needing certifications in the system they used at all which was a bit upsetting considering both managers were very positive about the interview. Nonetheless it was an easy interview, they ask about experiences and scenario questions. I don’t appreciate the lack of communication with HR and management so perhaps it is a blessing in disguise.
