2025' Student here, Pls help me with mock interviews

Hello Seniors Can you tell me how you prepared yourself for the interviews Any server subreddit where I can find Someone for mock interviews

I can take mocks with my friends, but the real issue is my anxiety spikes and everything goes in vain when taking an actual interview

I have lost 2 opportunity till now because I wasn't able to explain my projects

Pls help

And in return I will give back to the community by helping my juniors Once I reach that level

Thanks in advance
