I need some advice from experienced seniors here. I am trying to apply for a civil service job (2nd lower, general degree). Is it difficult for 2nd lower grads to get a job in civil service?

Also, I mass send to any openings that I am interested in. But because I have no specialisation, I end up sending alot even within one same company. Could that be the reason why I don't receive any response from the HRs in the stat boards/ ministries? What would increase the chance of one getting noticed?

Thank you!
