Pros: Arista is growing really quickly, which means there are always new and interesting problems to solve. The engineering team is very good, and management is committed to solving problems the right way (no quick hacks to get a feature out, use automation for building and testing). There is very minimal management, and engineers are encouraged to lead and complete their own projects.

Cons: Quick growth means Arista has lost most of its start-up feel, as much as management is fighting that. There is some tendency to see engineering as a sunk cost, and everything else as expensive.

Pros: Working at Arista Networks is a real pleasure in life. People are smart, ready to help at any time, come from everywhere in Europe and outside, and are socially really open. The office in Dublin is really nice. There are snacks, events, and everything you need to be happy, including a recreational room. The domains you can work on are multiple (infra, application, routing software, platform software, ...), and this is a really good point. You are free to work in any team you want, and free to change teams.

Cons: Arista Networks deals with software engineering offices on the West Coast and East Coast of America, Dublin, Ireland, and Bangalore, India. It can be hard or take time to schedule meetings or agree on solutions with every office sometimes.

Pros: - Talented people. (Warning: They might not continue here for long)

Cons: (In addition to the cons mentioned by the US employees) * Infrastructure is equivalent to old government offices in India. * PTO is 10 per year. * Expectation of working all the time without proper facilities. The company doesn't even guarantee parking for two and four-wheelers. * No additional perks (internet, telephone, cab, food coupons). * Medical insurance coverage is not top-notch. * Office location: Commute to and from the office in peak hours is a real pain. * No fun activities. * No US transfer. * Salary is 50% below industry standard.
