RigUp Content Associate interview questions

They contacted me via email to set up a time for an interview, I filled out my available times and days on the form, as well as emailing them the following day to confirm. They never said anything. The next (and only) communication I received was over a week later saying that they had hired someone else. Please don't contact me and waste my time if you're not going to follow through with an interview. Very unprofessional.
