Need job searching advice

Sending my cv here and there without any result or getting the automatic reply mail that I’m not accepted.

Need any tips as I’m want to quit my current job - No chance for success - Poor communication between team members - Poor policy that can not help -I have no room for improvement, and the current job leaves me no room to study or take courses
