need genuine interview advice

Final year student here,

I have been able to clear multiple oas and given quite a few interviews

fairly confident with dsa cs fundamentals and my projects but I keep struggling to convert the interview rounds

i feel one of my biggest gaps is articulating what I know clearly and using the right keywords that interviewers expect

For those who have gone thru something similar wht actually helped u improve ? any genuine interview tips, preparation strategies or things u wish u had known earlier wld be really appreciated

aand wat helped you transition from clearing oas to actually converting interviews?
