Medior employees.

Somebody else

Just like with profits, big tech probably beliefs it can just borrow them from other big tech companies. There is no visible shortage if they shuffle them around really quick in the stupidest and most dangerous shell game of all time.

easy, hire outside the company, post listing "senior engineer wanted, x amount of experience required, plus X amount of years in this skill set,,,etc. they do this for other tech and stem positions too. In order to avoid having entry level/junior employees, instead trying to save money by having a few skeleton crew of senior engineers or phd/MS holders, while neglecting FOB graduates(except for requiring more experience than needed for that low level position)/.

When a daddy senior dev op and a mummy senior dev op love each other very much....
