Pros
You work on things at scale. Many of the challenges that smaller companies are afraid of wasting their time, over-optimizing for, are crucial here. You're trusted to do your work independently and given support when you ask for it. Engineers (and all team members!) are completely involved and relied upon during project planning - so you always have a say in what your team will work on. Flexible remote working policy (e.g. expecting a delivery at home today, traveling, etc.) Travel opportunities to work with teammates or cross-teammates from other offices
Cons
There is a chance some of your work will be on legacy code (Java 8, groovy, grails, angular 1.x), but this is quickly changing and as of late 2019 many services have upgraded to a newer Java (11+) and/or latest frameworks (React, Spring). Fragmented frontend code. TW has taken a "microservices for frontend" approach which is more difficult to work with (versus the ease of developing a true SPA). Team structure happens organically which makes sense to those involved but looks quite strange from anyone trying to understand where to go for specific help. Some times it's very obvious and other times it's not. Too much information. There are hundreds (if not thousands) of nontrivial initiatives going on at once and keeping abreast is challenging but somewhat expected of you (to a degree).
