It’s interesting that many got phone calls for interviews, in my case I only got an email (at like 6:30PM) and that was it.Congratulations!
I got a call from an unknown number on 17 Feb (I am so bad at picking calls and it was a lucky moment that I had phone infront of my eyes).
Re your comment about email address, they just wanted to confirm if the email address is correct.
Keep us posted and good luck.
