I applied on December 3rd and got my email saying I got in on the 11th. I will say a specific PI there and the chemistry graduate recruitment coordinator had personally reached out to me after finding me on linked in (on Nov 29th) so that is possibly why I got my acceptance so quick. I got the official offer letter December 16th.
I didn't have an interview and haven't heard of anyone having interviews but from what I understand it is uncommon in chemistry. I believe they are on break so don't stress too much! The PI's there seem to be great about responding ASAP so reach out maybe? Keep me updated and good luck!!
