I am a 4th year law student from India. I will be graduating in 2023. My CV so far is decent, nothing extraordinary. I want to pursue my LLM from a foreign university. How important is the CV really? I understand that some colleges really look at your CV but otherwise, will a strategic effort to crack the SOP(or whatever its equivalent is) and the interview suffice?

In simpler words, how much weightage will my vision and the way I conduct myself in the interview have as opposed to my CV and grades?

And if the CV is all too important, is it realistically possible to start working towards it in the 4th year in order to apply next year?
