Lots do monthly/quarterly vesting. But all have 1 year cliffs. With the idea that you get nothing if you don't last.
I had the wonderful experience of being hired at Google many years ago, and pulled into an SRE role. I was in the roughly half that they do that with that don't work out. And I didn't work out for exactly the reason that I initially expressed doubts about. (I don't task switch that fast - not a problem in a SWE but a major problem for an SRE.) I was let go 5 days before my 1 year cliff.
That is one of the reasons why I, personally, discount equity compensation.
