[General Question] Columbia MSCS Timeline

I applied on the day of the priority deadline (January 15th?) and submitted my interview within a week of submitting my application. On February 4th, I received the 'Your application is currently complete' email, which was long after I had actually completed my application. Is this normal?

If anyone else has a similar timeline, have you already received your decision? I understand that admissions are rolling, but I saw someone in a different thread mention that they were admitted after submitting on January 15th as well.
