Yes, I got one as well... I think it was "replying" to an earlier mass email they sent three days ago that said they had invited "a number of" applicants to interview but the original one wasn't explicitly clear that that number represented all of the interview invites that are going to be sent out. I bet some people contacted them for clarification in the last few days so they just emailed again to make it clearer that all interviews have been sent out.
