Exxon is a dumpster fire inside of a house fire. Their PIP system promotes people throwing each other under the bus to try and get a higher rating (I was rated at the top, and left partly because I wanted nothing to do with this system). On the R&D side, the culture is absolutely abysmal. Something like 80-90% of people cannot develop an idea to commercialization, and the middle management has no clue. In 2020, they laid off or force retired the majority of their age 55+ employees, many of whom happened to be the most experienced and most knowledgeable. Now, they literally cannot design anything at the commercial scale without going back to these employees for help (many in engineering went to Becht). They're currently relocating their main R&D facility from New Jersey to Houston, which will cause about 50%+ attrition, many of whom are also long-time employees. It's well known that this does not even have a positive effect on finances or operations, it's a power play from management.
At this point, I'm not sure there are many good employees left. Exxon will have to grow via acquisition, which it's already trending towards. If you want to play the games, do nothing useful, and collect a high paycheck, it's the place to go. They're also outsourcing most engineering and projects to asia, so they truly don't care about their culture or quality. I'm sure they can drag this out for another 10+ years, at which point I hope they're overtaken by companies with true leaders that actually innovate.
