Doordash - promotions/refreshers

I'm considering a new grad position at Doordash. I'm wondering how the company is in terms of refreshers and promotions? This may be a general question for all companies too since I don't know how promotions work anywhere else. What's the next level after new grad and how long should you take before you get there, if you were to stay at Doordash, and how does it compare to other places? TC: >~190k, idk how to calculate how RSUs factor into tc #doordash #newgrad
