Pros

A few people have extensive expertise in their domain, and you can learn a lot of details from them. Massive infrastructure is to develop reliable and well-tested solutions. Social events such as regular hackathons, happy Fridays, and charity. VHI insurance. Free snacks for daily carb-loading and stress binges.

Cons

Completely rotten culture. (Or don't mind seemingly happy faces.) Having engineers at the top compensates with a lack of management skills. The team leads don't want to take any management problems and simply ignore them. Toxic individuals spread negativity around, dismiss everyone in front of the whole team, and then chase them with microaggressions. I, personally, had to visit mental health specialists and was about to proceed with a legal case. The management is totally disconnected from HR. No proper investigation is done in case of harassment. Reporting doesn't help, and incidents are turned in favor of management's friends and their favorite employees. There are no hikes. Management doesn't trust their employees and discuss neither current level nor career perspective. You are treated as a child, and you are being parented by someone "wise". You won't be able to build long-term plans with such company. Don't ever think about an L1 visa; the company doesn't offer it. The company structure is not flat and full of politics. Being ambitious and enthusiastic is not welcome. You can start a side-project, approved by the CTO. However, you will experience huge pressure from people playing politics and trying to break you mentally. Don't expect any transparent communications. Everything will be decided without you just like you were a small child. Most people prefer to hold their places quietly and stick to unspoken rules of authority. They have no courage to support anyone. Although infrastructure is great, it is really slow, doesn't allow fast iterations, relies on a proprietary SCCS, and morally obsolete. Hackathons are a joke. Their purpose is to entertain employees with silly gaming projects or never-finished projects: no real engineering is appreciated. If you are a C++ developer, don't waste your time. Otherwise, you will have to use only a tiny subset of C++. Furthermore, you will be forced to use a proprietary language that gives you non-transferable and completely useless skills for your further career.

Pros

It's been a year since i joined Arista and wrote my initial (5star) review. Since then i still think there is a lot positive about Arista. The people make the place. Purely technical interviews mean you are working with a diverse cross section of people who understand their work. I have interesting conversations every day. Hands-off management leaves you to do the right thing. Quality beats quantity. This also feeds the helpful culture in the teams here; People are not competing with each other.

Cons

I can't comment the average compensation package as there is no visibility into how these are calculated. When asked, senior management mumble something about magic calculations that they are unwilling to explain so I presume they just roll a dice. Performance review is based on peer feedback (which i thoroughly agree with) but the results are not disclosed so it's impossible to measure your own performance against those you work with. The tool chain relies on a proprietary programming language which is largely undocumented. In some teams this language will provide the base structure to all your code. The lack of documentation and proliferation of poor implementations elsewhere in the codebase makes it very frustrating to work out sensible design patterns. Despite presentations by senior Arista engineers, testing is not very well implemented here. "Unit tests" typically test huge objects. Since the proprietary language they are written in does not allow mocking and makes it very complicated to test individual class methods a single failing "unit test" test could be caused by any one of 100s of methods, 10000s of lines of code. Tests are also full of random numbers so if a particular test fails, just keep re-trying it until it passes.

Pros

Company employs great engineers and has a very relaxed culture where employees are responsible for their own work. Company prides itself on writing quality code and producing high end solutions for their customers the likes of whom include Netflix, Spotify, Facebook and Ebay.

Cons

Company operates a very flat structure so it may not suit engineers looking for a management position.
