Have you watched the documentaries on the Fyre Festival?Everyone in the company can be honest but if the top isn't then it doesn't matter. You can't really know that up front.
Fret not. I was a naive emphatic workaholic my first two years out of college--working as an investment banking analyst. It's taken me ten years to figure out that I wasn't honest with myself (or others) about what I wanted, and I've paid a price.
