Citizenship

Hi, here is my experience until interview:
applied from Austin ,TX
11/08/2016(election day)--> mailed n400 form
11/09/2016 --> USCIS received mail
11/17/2016 --> check cashed
few days after(dont remember the exact date) --> received the notice
11/26/2016-->received finger print notice
12/08/2016-->finger print done
1/25/2017--> status update online on USCIS portal --> on jan 25th 2017 "your interview was scheduled,we will mail you"
1/31/2017-->received the interview notice with date and time --> 03/08/2017 at 1:35 pm at San Antonio field office
03/08/2017 --> went to the field office around 1:00 pm,was called at 2:30 pm.
very general questions--> civic questions, made me read and write one sentence,all the general stuffs from n400 form. was out in no more than 15 mnts , the IO was in such a rush , she dint ask for any documents (although I had all the supporting documents with me).
she just handed me the paper which had below checked and told me to wait for the mail which might request for documents or might include oath ceremony date
-->you passed the English and history test
-->decision could not be made yet.

I know it is too early to be impatient(just been 3 days after interview) but just out of curiosity, if any one has been on this situation and have received the mail within in a short time period.

Good luck to everyone who has been waiting .
