Pros
Great company culture, everyone seems to genuinely care about the other. There is little pressure, yet people are very responsible and accountable. Small teams with strong focus on a single technology stack (no interdisciplinary teams), making it easy to focus on your area of expertise and excel. There is a unified technology stack throughout the company, which could be a good or bad thing, but it makes things much more straightforward and much easier to get help internally. The diversity culture is strong and everyone feels welcome.
Cons
The diversity culture can make one feel pressure, especially if you don't believe in personal pronouns or simply don't want to have stuff like that in your name. Every meeting or presentation starts with people introducing themselves and their pronouns. This can make it very uncomfortable for people that don't want to do it. There is a strong push to use VS Code as a frontend engineer. All the company's tools are integrated with VS Code and they provide no license to Webstorm, etc. There is a generous education budget, but it does not cover conferences or books (unless the books are part of your studies). There is a free books program though, which covers one e-book (less than $35) per month. The company does not sponsor conference attendance or language courses, which is sad. There are lots of internal tech and tools, which you will spend the better half of a year learning. Given these tools are internal to the company, this knowledge and any experience you gain with these tools will not follow you out of the company. There is an internal version of everything, from React, to Webpack, Jenkins, Babel, Moment, etc. New language features (like async/await) are not available because the internal version of babel is outdated. There are lots of frustrating problems like these.
