Pros
Oracle is a terrific brand to work for, when working in the IT industry, if Oracle is in an account, it's never going anywhere so there is tremendous upside to continue to sell into the account. As part of an acquisition I was given better benefits and resources to sell. I was also able to tap into their tremendous sales force that has great reaches into multiple contacts within accounts.
Kontras
Their existing software sales force is very hard to work with as they are controlling and look at those who were acquired by Oracle as direct reports when that could not be any further from the truth. You receive a sizeable car allowance a month but can not expense mileage unless you are traveling an exuberant amount of miles a week. My major issue was the lack of ability to move within the company for 6 months after the acquisition and thus no pay increase.
