What's one thing you wish you'd known before joining Oracle?

Oracle does not promote from within nor do they tread petformers. Negotiate the highest base you can because you will never get an increase and that limit any move by tying increases due to new positions to a low factor above the low base you start with. Managers are ignorant of how to advance and promote employees. Oracle is a good logo to build your resume but not a career place. Lots of bullies. Since managers are not empowered to lead or motivate you have many laggards who just take advantage of the company but are not contributing to a strong respectful environment. Oracle should bring all of its US support back to the US. Quality would go up and their corporate respect would increase. It is an inhumane machine.

Oracle does not pay well or promote from within. They are a throwaway culture where employees are a nuisance. Poor pay

That you have to self learn. Do not expect you would be trained to do the job.

they have a terrible self service culture and don’t even supply you with a mac :-(

The bullying culture. It is a horrible place to work.

... to keep job searching.

My boss is a bully.

I knew almost everything

The real Culture.
