L1, L2 Visa

Hi, my L2 visa got approved yesterday. My husband is already in US, so went alone for stamping my visa.
My passport, DS160 confirmation, interview appointment letter, HDFC receipt (embassy copy), husband's company's BEP letter, husband's approved I-129 copy, I-797 copy, husband's valid visa and passport copy were taken beforehand itself and submitted to the VO before my interview.
Questions asked during interview :
Me : Good morning Ma'm
VO : (Smiled)..Good morning, How r u doing?
Me : Fine Ma'm
VO : Ok, now tell me why do you want to go to US?
Me : To join my husband and spend quality time with him
VO : How long have your husband been there in US?
Me : Mentioned all the dates of his travel including the previous ones and duration of stays
VO : How long are you married?
Me : Since XX months, mentioned the date of marriage
VO : Who is your husband's employer?
Me : YYYY company
VO : Where does your husband stay in US?
Me : YYYY city, YYYY state

Me : Sure Ma'm
(typed something in keyboard and read something on the monitor for 2 mins, checked my huband's visa copy and I-94 form copy)
VO : Do you have any kids?
Me :No Ma'm
Then came out the golden words from the VO "We will approve a visa for you to travel to US"
Me : Thank you very much Ma'm. Have a nice day
VO : Smiled , have a nice day.

No other documents were asked from me regarding marriage like marriage certificate or marriage albums although carrying them is a must for all.
Pls speak confidently, look into the eyes of the VO and speak, and the visa is yours...
