Total compensation means $700K, some of it being cash, some of it being stock. Company cars are pretty rare in the US, since basically everyone has a car already.
Company cars are really common in some industries, very rare in others. Ive never heard of it in tech, but I know people in sales that its just part of the gig.
I've not owned a car in 7 years thanks to my engineering gig coming with a work truck for getting around construction sites. Quite enjoy that aspect of it.
Roblox will not be issuing stock options now and likely stopped doing so for 4+ years already. The equity component of compensation now will be actual stock (shares) and not options.
Another commenter mentioned that cash/equity now has a 33/67 split meaning $700k tc would likely be $230k cash and $470k stocks
Total Compensation is the sum of all the different ways you are paid monetarily. This includes, but is not limited to: Base salary, Bonus, Equity (stock) compensation, Benefits
