I always encourage fresh grads who have limited marketability to expand their horizons. There is no need to keep obsessing over joining a bank.

You don't sound like you really have passion for any particular banking role and so far your job hunting seems mediocre. Time to broaden the net to other industries and even consider non-finance jobs.

Focusing on an industry where supply far outweighs demand with an average fresh grad CV isn't going to get you anywhere.
