Asking for advice

Hi everyone, I am a 2023 graduate from tier 3 college currently working in a service based company but I am not really satisfied with it because I believe I could have grabbed better opportunities in campus placement but due to stupid rule of TPO they did not let me seat for further companies and I want to learn new technologies but I am not really getting opportunity here. So, i am looking for better opportunities.Anyone got suggestions where to apply and what to prepare. Also should I do any certification .
