I graduated with a degree in engineering (a line with less frequent jobs rather than the more popular engineering lines) with a really poor CGPA (less than 2.2). The university I graduated from wasn't a good one (one of the non-research government unis) and the lecturers were sub-standard, but I managed to pass all subjects eventually. My question now is are there any chances for me to make it to a reputable company with that degree alone? I have been called for a single interview so far (in 9 months of applying) by a Chinaman factory with a really poor working environment and I'm not willing to work in such a place. Would you recommend I do a master's degree instead and put in the effort to cover the CGPA blunder? Will that land me a better job at better companies?

Thank you for the advice. I'm pretty much aiming for process / manufacturing as a stepping stone (but with the job scope of an engineer of course). It doesn't matter if it's an MNC or not, so long as I can gain the relevant experience to push me higher on the ladder. I don't mind competing and proving myself if need be. In fact I'm certain I can do much better had I gone to a different, more reputable university than the one the government sent me to. I can't say I have much interest in sales or insurance right now. Also I feel like it would be a waste of my degree if I end up doing something that's not related to what I studied for all these years. However your tips and advice is duly noted.
Ah I see. That sounds like a great place to work at, though I'm not in the electrical/electronics line. Surprised to hear that they don't prioritize CGPA. Huawei is a huge company with operations in other countries. Good info, thanks.
