I'm one that had enough. There was no focus on the future, just trying to survive. Left it all behind. The question is not "why do you want to leave Oracle?" but "Why would you want to stay at Oracle?"
Answer that truthfully.
If you are reading this, you probably already know the answer.
Not many companies care less about their "Human Resources"
You are working on new stuff, or being leveraged against it.
Are you working on new projects or being pushed into supporting older products?
Change is great..... if YOU initiate it......
If you are happy then I'm happy for you, otherwise believe in yourself not the BS you are told to keep you where you are.
