yeah if you look at banking, people with titles like Vice president or Director leave all the time in relatively large numbers and it means nothing. C-suite is another story.

Tesla isn't a bank though. People have those titles in Finance because they have ownership over a particular product division, of which there are many. Consumer loans, corporate paper, fixed income, export-import financing, commodities trading, etc.

Also statistical comparisons on open positions for these absent positions. Have there been management consolidation? What impact has there been to the functioning of the company?
