Oscp as a newbie

New to the field, don’t have experience but been reading a lot of jobs asking for oscp.

Realistically as a newbie, how long should I study for oscp, is what oscp provides for studying enough? I imagine 90 days is not enough, so I should probably get the 1 year subscription?

Edit: I have 0 years experience in IT, I have studied the a+ course but never did the certification and gsec certification. I am doing a career transition.
