Pros
You are selling the best products in the industry. When competing against other companies to win a deal, you have an advantage, because everything Oracle owns is the best. It is easy to get in the door with customers because everyone uses at least one product within the Oracle product stack. It is a good thing to have on your resume.
Kontras
This is a very cut throat company and they are not known for treating their employees with the greatest of respect. Management does not have the upmost in talent. They are incredibly cheap with things such as travel, awards, team lunches. The processes to close a deal are too overwhelming. For eg. you have to negotiate contracts with the lawyers on the customer side, but Oracle will not put a lawyer on the phone.
