That's entirely possible, from the email I got it seems like this is normal for Caltech.

I got an interview for Caltech Biology yesterday! I was not expecting that...but I have been running on the philosophy "if you don't apply you can't get in." However it is odd, they do a 15min interview next week and then if they like you a more formal interview in January.

I applied to either the biology/biomedical sciences, immunology or microbiology programs at these schools: UCSD, Rockefeller, Boston University, Tulane University, USC, UCLA, Stanford, UWashington, WashU St. Louis, Vanderbilt, Emory, Columbia, Harvard, Mt. Sinai, Caltech, Scripps I received an interview invite for Tulane on Dec 3 after sending my app in Dec 1 (was very surprised by that turnaround! but my lab collaborates with Tulane a lot)
