Pros: The environment is really good to work in.

Cons: It can get stressful, and very strong people around you sometimes make you feel you're behind.

Pros: Pay is really good, and coworkers are okay.

Cons: The culture is rather toxic and sometimes coworkers are toxic too, due to PSC.

Pros: A big tech company that still moves fast. You get to do lots of data science and analysis yourself on your own features to see if things are working or not. You have a suite of offices around the world to hang out from, even though I think now it’s mandatory three days at the office.

Cons: Building fbios takes about 20 minutes on a cold build, but it can be more or less. It's still not compatible with Buck 2. Working with Objective-C++ is a nightmare, and the process to switch to Swift is long and low priority. It's definitely not as easy as it was for Android developers to automatically have their code switched to Kotlin. Data analysis is messy if you don't set up the experiments perfectly. You end up presenting to people with incomplete data and having to come up with persuasive reasons for XYZ. It's all quite shaky and uncomfortable. No matter what you do, some experiments you run will inevitably be unbalanced, and then you have to start over and wait another week.
