Oracle

Depends on the team that you are in.

Everything depends on your manager.

I happened to be under an incompetent manager initially, and didn't like it. I shifted to a team with a very competent manager, and really liked it.

Very good functional learning.

Lack of flexibility to move to different teams inside Oracle (if they are under a different Line of Business – say consulting, presales, or product management). That was the biggest problem that forced me to quit.

Plus, no standards maintained across the teams in salaries.

Should be mature enough to realize that employees might prefer to gain exposure in different areas. The company has opportunities, but often it's a tragedy that you have to quit and apply again to get considered for a different position in a different line of business.
