Fioyegold, let me share someones experience with you. A friend of my friend once had an interview with SLB and it took 2 years after the interview before he was asked to resume work. Am not saying that is their policy, but someone told me that at the end of that period when you re finally called, they'll like to what you have done to develop yourself in the time past. So maybe you should just run some certification programs and maybe do a masters program. It's all about self development.
Have Fun!
