Failing interviews

Hey all, I feel so shit at the moment. I’ve failed 8-10 interviews so far, out of job since a year. It seems like every interview they ask a totally different set of questions or scenarios. Whatever I prepare gets me maybe 50-60% of the way, rest are all new questions and I fuck up or I’m not able to fully give them an answer.

What makes me feel even worse is that, lot of people aren’t even getting calls at the moment and here I am speed-running every single opportunity to failure. I’m so done at the moment. No idea how to proceed or what to prep.
