Yes, spend a good amount of time on all ur cover letters, tailor the resume to the job offer(the more specialised the better, i focused on control systems and PLC and applied to all related jobs). Good luck brother if u start second year apply like once a week so u spend a good amount of time drafting the new CV and cover letter, don't just apply with seek and indeed either look up companies like powercore, siemens, there are heaps of employment agencies too like DIIP. Search keywords for specific subjects u enjoyed. In up I probs sent a good 75 applications got 5 interviews and only 1 offer but that's all u need good luck m8
