Thank you for your quick response!
I was thinking about working for big tech. Should I go about culture and tech stack? I was doing frontend (vue) and backend (node) and a little bit of flutter.
Given the demand for tech of all types you'd have to try hard to pick the wrong thing. Regardless, you'll probably move on to some other stack in 3 to 5 years.
1) Give it your best guess / shot now.
2) Embrace the fact that you'll always need to be learning :)
