Arista Networks

What Arista Networks does

Arista provides "client to cloud networking services for large data center/AI, campus and routing environments", built on its EOS operating system. The Etherlink AI portfolio spans 100G-800G switching, and on Jun 16, 2026 Arista unveiled a 1.6 Terabit generation for AI fabrics. AI datacenters are the marquee growth driver; CEO Jayshree Ullal argues "Ethernet is the eventual winner" for AI networking. Public on NYSE:ANET.

What it is like to work at Arista Networks

BuiltIn frames the trade-off as "high autonomy and flexible schedules exchanged for an outcomes-first culture that can spike into off-hours." Glassdoor Santa Clara composites to 4.2/5 with 82% recommending to a friend, and Flexindex lists a hybrid policy with two corporate days in office. Culture is flat, engineering-focused, and collaborative, with periodic off-hours intensity.

What Arista Networks pays

Public-company RSUs are core to comp: Macrotrends shows stock-based compensation of $933M for the twelve months ending Mar 31, 2026, up 18.8% YoY. 6figr reports an average around $223K, with a range of roughly $141K-$592K and a top-decile near $592K. One Taro review asks the company to "be more transparent, particularly around compensation and RSUs," so probe grant details in negotiation.

How hiring works at Arista Networks

DSAPrep's 2026 guide reports roughly 63% Medium and ~5% Hard questions, with depth on linked lists, binary search, and graph fundamentals. Reddit r/Arista describes about a five-round process including onsite rounds. The bar rewards low-level systems and packet-forwarding depth over breadth, so networking and data-plane fluency matters more than leetcode volume.

Growth & trajectory

Arista crossed $2B quarterly revenue for the first time in Q1 2025, and FY25 (ending Dec 2025) hit $9.006B, up 28.6% YoY. Market cap as of Jul 1, 2026 was $206.64B — larger than SentinelOne and Zscaler combined. Nearly 28.6% YoY growth is rare for a $9B-revenue mature company, driven by AI-datacenter demand.

Risks to know

CEO Jayshree Ullal has executed significant insider sales — about $15.8M on Apr 23, 2026 and roughly $70M on Jul 31, 2025. There was layoff chatter in late 2024 but no official confirmation. The deeper structural risk is exposure to hyperscaler capex cycles: AI-datacenter demand is both the upside and the concentration risk.

Who thrives at Arista Networks (and who should not)

Thrives: networking and systems engineers with depth on packet forwarding, data plane, and low-level systems, and people comfortable with an outcomes-first culture that occasionally spikes off-hours. Should not join: candidates unsettled by CEO insider-sale signaling, those needing a rigid schedule, and engineers hostile to a "small-business operating style." It suits deep-systems builders who want AI-tied upside without account-by-account risk.
