Congrats IcAero on getting your 1st Interview! I'm still waiting for my call
what phone number did you apply with? Did you update them with your local number? Maybe you got called on a number that you don't have on?
I did not provide them with a local number until I got an e-mail asking me to provide it along with an invitation to the AT. So just check your e-mail if you never provide them with a local number to contact you with.
