Arista Networks Interview Guide
Everything we know about interviewing at Arista Networks: the process stage by stage, what each round tests, compensation by level, and reports from candidates who interviewed.
Interviewing at Arista Networks
What the process looks like, and what Arista Networks is really testing for.
Arista Networks runs a heavily technical interview loop. Across reported steps, you see recruiter screening, then live technical evaluations that mix coding, debugging, and systems thinking, with a final team fit and culture step.
What the interviews test is consistent with the topics they ask about: data structures and algorithms, Python, and low-level programming skills, plus system design focused on systems reliability and scalability. For roles that align, you also see topics like cloud computing and hybrid cloud, site reliability engineering, software-defined networking, ERP and ERP integration, Boomi (iPaaS), and optical transceivers.
Be prepared for a tight signal from your technical performance. The candidate reports show high difficulty overall, with 64.7% medium, 18.4% hard, and 1.2% very hard difficulty, and the aggregated offer rate reported is 0.5%, so you should assume you need strong execution across the technical rounds.
The interview topic mix includes multiple domain-specific areas beyond generic coding, including ERP and ERP integration plus cloud, SRE, and software-defined networking, so you should align your prep to both core fundamentals and the relevant domain topics for your target role.

Initial screening / phone screen

Technical assessment and technical deep-dive
Multiple roundsYou move into technical evaluation. Reported technical deep-dive steps include in-depth sessions with members of the Business Applications Team, and candidate reports describe live coding and debugging sessions that can be fast-moving and multi-question.
Onsite in-person technical rounds
Multiple interviewsYou complete onsite-style interviews with multiple technical rounds, described as covering low-level coding, system design, automation infrastructure, and behavioral fit. Candidate reports mention C or systems-style questions, Linux command-line tool design, and algorithm and data structures interviews, along with role-aligned domain topics.
Final interviews for team fit and culture
VariesThe loop ends with final interviews with team members to assess fit within the team and company culture. This step is explicitly reported as a culture and fit assessment rather than a technical deep evaluation.
