1- During the recitation: the follower should join the congregation in this stage only if they think they will have enough time to recite the Al-Hamd and the other chapter or at least the Al-Hamd, but if they think they will not have enough time to do this, as an obligatory precaution, they must wait until the Imam pronounces the Takbeer of the bow or enters the bow and then they can join the congregation.

2- While bowing: if the follower joins the congregation after the Takbeer of the bow or while bowing, they must perform the bow with the congregation and perform the rest as explained earlier.
