My firm made billions last year too and just laid off hundreds of engineers (a decent %) Some of the best engineers, those that I respected the most, went. People who make no sense. After last year's layoffs they told us they were "done" and it was "all behind us". Last year then turned out to a better year financially than 2022 (we have access to the top line numbers) You can't trust anything anyone above you in the…
As you gain experience, you get really good at parsing and identifying axes of flexibility in statements from the power structure. In general, professional managers in a power structure will always distort or mislead with any statements they make to turn any announcement into a steering opportunity. This is just how it is and it's really not about "trust", it's about manipulation.
Manipulation is _everywhere_ in the tech companies. Nothing is more amazing to me than an experience I had early on that woke me up: the day after I attended a meeting about how the company was working on a project that was incredibly unethical (think google's china search engine-level unethical or worse, like Nokia's building anti-dissident features into their 3g networking for Iran), I attended a company all hands where the entire message from every exec, including those that were involved, was about how we were a force for free speech, freedom, etc. I already knew but it was stark.
They also engage in constant attempts to blur things. Google, in particular, spends a lot of money to help muddy the job-vs-personal waters because it gives them power. For their first decade and a half, at least, they ran the whole company like college - extracurricular activities, etc. This wasn't just because the founders had no professional experience prior, it was strategic to make it very hard for people to leave (and when they started leaving for FB, that was to another place that was similar).
So forget about "trust" - start thinking in terms of "what is this person not saying, what is this person trying to imply without putting it in words, what flexibility are they reserving for themselves with their statements" etc.
