Meta Channel Operations interview questions

Fast response to setting up an interview, then a second one was requested for the following week, I had work travel so I was unable to move things around even offered to take the interview from the airport, they met me half way and scheduled a video interview even though I had limited time but was necessary as they wanted to make a decision to hire in same week. A month goes by and no feedback or response at all. Completely unprofessional for a company like Facebook.
