Meta RSU Query

I have seen blind post where people are complaining about tc going down due to stock going down. This is first time I will be getting RSU, so want to understand how they work.

Let's say I get 50k/yr rsu as initial offer. Now meta has quarterly vesting schedule.

Question 1 : When am I allocated #of rsu ? At the time of joining based on last month avg price or every quarter based on last month avg price and they vest in next quater ?

Question 2: If answer to first question is latter, does it mean RH, docu RSU allocation is different than meta and thus they loose money ?
