Left Oracle early in the year. Now interviewing data and cloud people left and right, and a consistent theme is that companies are migrating off of Oracle databases to Azure or AWS services (Google who? Sorry, Kurian).
We did interview ONE guy who had experience in OCI as a real customer (as opposed to an acquisition). To his credit, he loved it, but conceded it's "resume death".
In fact, working for a company that migrated to OCI (with some Azure of Office 365) is the primary driver for him looking... again, resume death.
