I'm assuming your question is loaded in an attempt to say "You haven't worked on any large teams then"
But I have, in a fairy large project (completely rebuilding all of Deere & Co's internal systems, upgrading from literal terminals to web app) with >100 developers merging in hundreds of PR's a week.
Ah yes, a 5 year, hundreds of engineers, multi-million dollar project to take 1980's terminal computer ordering system for millions of Deere dealerships and bring it to the modern ages through a web app is just a simple crud app that barely needs styling.
Do you ever just re-read your replies and think "I'm being ridiculous" and decide NOT to post it? You should do that more often.
