I’ve never worked at a FAANG but currently at a F100 in fintech, and as the product manager for our team, part of my role is to make sure our team is doing work that has quantifiable value.
But for ICs on the team they’re not penalized if I make the wrong decisions and lead the team down a negative path (however part of my role in being successful is making our team goals transparent to all the team so they can help course correct if my thinking is way off).
