Frontend Engineers what tools do you use at Google?

I am considering migrating over to Google and I know this varies a lot by product but what kinds of tools are you using for web interfaces there? I have friends who worked in chronicle (cyber security stuff for gcloud) and have mentioned in passing working a lot with angular. Another guy I know was working at YouTube (not sure which org) and he mentioned working with custom web components and an internal js library/framework organizing the app he works on. It’s a huge company so I know the stack can vary a lot but I’m curious to know what you guys are are working with in different areas. TC: 270k #tech #stack #google #frontend #angular
