citizenship interview completed decision is pending

[titan]

my citizenship interview was completed few days ago. During interview IO told me that my First name and last name is matching with some one else. so he told me whether I married with some other girls too or not? he told me apart from my current wife they comes up with two other name which I may married. But mean while he told me may I don't never seen them. I said yes I never come across this type of name girl and I told him I just married once. Than he printed one paper that I neve lied any official, I never married before, I married only once to my current wife, I have employment based category so I never applied on marriage base, some other thing related to immigration and we both signed that paper on front of witness and he told me that he will submit the report and if they will need something else they will send me the letter.
Is any one had same experience in the past. How long they takes in this type of case to make decision
Thanks

I had my interview Jan 16 2019 and I also had to sign a paper in front of a witness I just didn't know what it was for, My IO officer was a young girl she looked in her mid 20s, So I guess it's a declaration stating you're not lying during interview.
