For anyone who has worked for a startup (late stage, and 1.5K+ employees), have any advice on what life will really be like?

Being hired with a Director title, but I have heard that in a startup that may not really be the type of work you are doing as you really need to roll up your sleeves and get into the weeds. Not that I mind that from time to time, but doing that daily is not where I want to head next in my career as I am looking to level up in my career into a leadership role.

Any tips or insights appreciated!

My background is working for more established large companies with structure and lots of red tape which I don't mind actually.

Thank you!
