Judging from years past, the interviews were sent out sporadically with a week or two in between a batch of invitations, so I am not expecting to see any more invites for a few days.
Yep, the invites go out in clumps. They're probably be three clumps I would guess. When you get an invite has no bearing on your candidacy, last year I was one of the first to get an interview invite, but almost absolutely last to get an admit call. Its pretty random.
