Hi, I graduated from NUS Computing with 3rd Class Honour. I'm earning way above market the rate now. I am like you last time and I thought my future is doom. But life is full of opportunities. My advice is to strike the interview creatively. Don't use words that a normal interviewee used. And most importantly, please do research and homework before attending the interview. Interviewers like to seek your opinion about their companies. Hope it helps! If all else fail, still can sign on. If all smooth, 10 years down the road in service will make you live very comfortably...
