RSU grants are typically only in "dollars" at the very beginning, and the amount of shares is decided based on the date the grant begins. This is how people make tons of money if their company's stock explodes. I've had the good fortune of a 200k (divided over 4 years) stock grant turning into 450k, but this is nothing compared to what many people experienced in the last decade. Of course this can work against you to. Some peoples RSU vest lower than the price when the grant was issued. Another (usually small but no always) factor to consider is that sometimes it can take a month or two for the price of shares to get locked in. It's typically not on your start date, but at some future date after you start when the company issues all the grants.
