I want to ask suppose, I joined the jama'at in its 2nd rakk'at. I need to offer my 1st rak'at, so what should I do when the whole jama'at is reciting Qunoot (Dua of 2nd Rakk'at)?
Do I need to stand still or do I need to recite something?

Since qunoot is mustahab there is no problem in reading it with the jamaat (even though it is your first rakaah)
