Oracle is a safe haven for incompetent managers and so called team leads. I know a few ex-colleagues of mine who left Oracle to join other companies and were shocked to see how fast and agile other companies were.

It is not in Oracle's DNA to hold managers accountable or fire them for management blunders or shoddy management. So when some of these managers and team leads from Oracle joined other companies, they found much to their surprise that they were answerable to higher management for the state of the project they were managing. They could not keep up with the pace of development or having concrete responsibility, and returned to Oracle to live a purposeless but relaxed life where one would earn less but otherwise thrive in the company by doing little to no actual work.
