I was in the background as you. I was a specialist back then and i further my studies at one of the reputable University with SIT. Afterwhich i join one of the GLC till now doing engineering. The only thing i can say that it is harder than you thought. To be pretty honest with you, even till now, with ample exposure and experience in engineering field, i still couldnt get in to govt as they only gave interview chances to local uni no matter if the applicant matches the requirements. I have seen it myself. Well, im still trying. Cross fingers.
