Yep. That's what I had at Google. Was selling shares as soon as I acquired them (no issue with GOOG but I preferred more diversification). I recall there being some admin time needed (~2-3 months?) before I had access to said shares but as soon as I did all 2-3 months worth were "vested" and I started cashing out.
Monthly at Google, quarterly at Facebook.
The vest frequency depends on the size of the grant.
Some grants (small) once a year
Bigger - quarterly
Large - monthly
Can confirm that at G.
The only point of the one year cliff is to pay someone less, or keep a startup’s cap table clean. For a public company there would be no point.
The other point is to bind people to the company.
It's very similar to a sign-on bonus you can claw back in the first year or two.
