I see. Is the person you know in the department talking about this year? I also know someone in the department, but he told me there's no interview for him when he got accepted.
I just checked the result board. Someone got rejected by UCSD earlier this month, so it does seem they are making decisions at different time. I am really confused by the admission process in all these California schools. I applied to three schools in California, but I have heard back from none of them.?
