Work on whatever you believe will be best for the company.

Operate however you like; no one is checking up on you to make sure you're in the office, etc. You are treated like an adult, are highly valued, and expected to make your own decisions.

Benefits and perks are amazing.

You'll be working with very intelligent and efficient people.

This is a pragmatic company with very little time wasted discussing trivia.

Some of the tooling for developers is out of this world.

You can actually choose your own team at the start and switch teams very easily.

Some infrastructure for developers on the less beaten path is not as mature as in rival companies.

Having no public-facing cloud services like AWS/GC, the FB services are less reliable.

Keep the hiring bar high.
