I actually work in finance reporting, as a data engineer, at FAANG.
Interesting that you think the entire data team is double & triple redundant.
It's almost as if you're the one lacking knowledge.
Speaking as someone who previously worked at a company blatantly committing fraud, the CEO hand-picking the entire data team was instrumental to said fraud.
Maybe that's just my past causing the suspicion. If he laid off 75% of the data team, I'd be less skeptical. Maybe he thinks they're double and triple redundant, as you say. 100% is extremely suspect, though.
As someone who runs Tesla, which has a large data eng team, he knows the entire team isn't useless.
