Pros: Internal tools are well integrated. Continuous code delivery is very nice.

Cons: PSC culture forces you to optimize and focus on short-term gains at the end of June and December. Fighting for scope is not uncommon if you want to perform at your level or get a promotion. If you have a good manager, you will be mostly spared from politics. If not, it sucks to be you.

Pros: Talented engineers everywhere. You’ll learn a lot if you survive the pace. Top-tier tools and infrastructure; technically, everything works beautifully. Compensation is excellent — they pay well for your time, sanity, and weekends. Remote flexibility (when allowed) helps offset how draining the culture can be.

Cons: Meta confuses urgency with importance. Everything’s a fire drill, even the things that don’t matter. The “move fast” mantra has turned into “move constantly.” There’s no real space for deep work or thoughtful engineering. Performance culture rewards visibility over substance — those who talk loudest get ahead, not those who build the most stable systems. Managers often act like political players instead of technical leaders. Feedback loops are shallow, and actual mentorship is rare. Genuine work-life balance doesn’t exist; burnout is normalized, not solved.

Pros: Good product infrastructure and strong colleagues.

Cons: Threat-driven culture and not too many opportunities.
