It seems that 30 day thing only applies in certain countries. For most people in the US, you either sign up for FEDEX notifications to warn you of an impending overnight delivery from Oracle, or you just get a “surprise! You don’t have a job” phone call/ email from your manager.
In either case, they do not want you because you are either too old, do not have the skill mix they want (the oracle internal training is just glorified marketing decks that no one takes seriously), they are wiping out support for your product or you just cost too much in salary and benefits.
Keywords are They. Don’t. Want. You. Period
No number of internal job postings will save you.
This is how all the big old software companies are operating now.
Just ask the folks at Eye Bee Em. Big expose on how they like to cut ”grey heads”, even the ones who are at the top of their game. Google it to see how these big old companies are getting away with age discrimination. Don’t doubt for a second that Oracle is doing the exact same thing. Heck, The Turd practically invented this strategy !
Move on. These old dinosaur orgs do not deserve you.
