It took me about 1 year to get out of O, but I got out. After 6 years at O, working for my hero, Larry Ellison, I felt so dirty. Everything was such a scam, lying and cheating and audits. I would never do this to any of my customers, but everyone around me was glad to, in order to make a their quota and a feeble paycheck. Class of, let O have them. Good for them.
Do yourself a favor, and try your hardest to get out of there and you will feel like a fresh shower in the morning and a career that can move you forward.
