pulse shaping comes first at the transmitter and then comes CP(always
the last step).

RRC. Yes a corresponding matched filter is required to maximize the
SNR and make use of the "information in the pulse shape" i.e. which
sample to weight more or less.

Mention the literature you are referring to or the context in which
they said so.
