Technical Program Manager, Infra Interview at Meta

Hi, I'm Payments Product Manager and have a Bachelor's in Computer Science. I've had limited interaction with technology teams due to mature products (one of the reasons that I want to move back into tech.) Would really appreciate any guidance on how I should approach technical project retrospectives and any general guidance for the interviews. TC: ~70k equivalent YOE: ~5 (4 payments strategy/consulting, 1 product management) Thanks! #tech #tpm #meta #finance #product
