Intern Software Engineer Role

Role Overview

The Intern Software Engineer role at Arista Networks is designed for students or early-career candidates who want to build real software for production-grade networking systems. The work centers on the Platform team and related engineering efforts, with a strong emphasis on C and C++ development, Linux systems work, and infrastructure software.

Day to day, interns contribute to code that helps support networking ASICs, Linux user-space and kernel components, configuration management, and automation tooling. That means your work can affect how network devices behave, how they are configured, and how reliably they operate at scale.

Detailed Responsibilities

• Build software components for platform foundations and networking infrastructure.
• Write and debug C/C++ code for systems-level features.
• Work with Linux user-space and kernel-level functionality.
• Support configuration management workflows using Go and Python.
• Contribute to tooling around YANG, OpenConfig, NETCONF, and RESTCONF.
• Use Git, Gerrit, Jenkins, Slack, and Trello for development and collaboration.
• Participate in code reviews and incorporate feedback from senior engineers.
• Test changes thoroughly before integration into larger systems.

Day-to-Day Workflow

A realistic internship day at Arista Networks usually starts with reviewing tasks, checking messages, and aligning with a mentor or team lead on priorities. From there, you might spend the morning reading code, reproducing a bug, or implementing a small feature in a shared codebase.

Afternoons often shift toward debugging, writing tests, or preparing a patch for review in Gerrit. Because the role is systems-heavy, expect to spend time understanding logs, tracing behavior through layers of software, and verifying that a change does not break downstream functionality.

The workflow is collaborative but technical. You are not expected to operate in isolation; instead, you learn by pairing with experienced engineers, attending lectures, and contributing to real team deliverables.

Tools and Technologies

• C and C++ for core systems programming.
• Python and Go for automation and configuration services.
• Linux, including user-space and kernel concepts.
• Networking protocols and standards such as NETCONF, RESTCONF, YANG, and OpenConfig.
• Build and collaboration tools like Git, Gerrit, Jenkins, Slack, and Trello.
• Infrastructure concepts involving gRPC, SSH, SSL, and embedded systems.

Skills and Requirements

Technical Skills

The strongest candidates usually have a solid base in C, C++, algorithms, Linux, and networking fundamentals. Since this is a systems role, it helps to understand memory management, debugging, concurrency basics, and how software interacts with hardware or low-level operating system services.

Experience with embedded systems, distributed systems, or automation tooling is a plus. If you have worked with Python or Go, that is useful because the role includes configuration and infrastructure work beyond pure low-level coding.

Soft Skills

Arista clearly values curiosity, problem-solving, and a willingness to learn quickly. Communication matters too, especially when you need to explain a bug, ask for help on a complex code path, or respond to feedback from a code review.

Teamwork is essential because the internship is structured around mentorship and shared engineering practices. You should be comfortable receiving critique, iterating on your work, and staying organized while handling technical tasks with precision.

Experience Expectations

Arista’s internship description suggests that the company prioritizes aptitude over perfection. A graduate degree is not required, and the listing emphasizes programming interest, which means strong students, self-taught builders, and candidates with hands-on project experience can all be competitive.

A portfolio is especially helpful if it shows systems thinking. Projects involving networking, Linux internals, C/C++, or automation will stand out more than generic app work. A strong GPA can help, but real evidence of technical depth often matters more.

Salary and Benefits

For Poland-based remote software engineering internships at Arista Networks, a realistic market-based estimate is roughly PLN 6,000 to PLN 12,000 per month, depending on experience level, team, and internship length. Public listings do not always reveal compensation, so this range reflects current European systems-intern benchmarks rather than a confirmed posted salary.

The benefits look unusually strong for an internship. The listing mentions a personal mentor, Arista Prep training, weekly internal lectures, and access to global hack-a-thons. For end-of-studies internships, there is also a credible path to a full-time permanent offer before the internship ends.

That conversion potential is one of the biggest reasons candidates pursue an Arista Networks internship. If you perform well, the internship can become a direct entry point into a long-term engineering career.

Arista Networks Hiring Process

Step-by-Step Hiring Stages

1. Application: Submit your resume, academic background, and any relevant project or GitHub links.
2. Screening: Recruiters or hiring coordinators review your fit for systems programming and internship readiness.
3. Assignment: Some candidates may be asked to complete a technical exercise or coding task.
4. Interviews: Expect one or more conversations focused on technical depth, problem-solving, and team fit.
5. Offer: Successful candidates receive an internship offer, often with details on team placement and timing.

Application Timeline

Because the deadline is not mentioned, the safest approach is to apply as soon as the role appears. Internship hiring at a company like Arista can move in waves, and strong candidates are often reviewed early. In practice, the process can take anywhere from two to six weeks depending on interviewer availability and the number of applicants.

Screening Methods

Applicant tracking systems will likely look for keywords tied to systems and networking work. Terms such as C++, Linux, networking, embedded systems, algorithms, Python, Go, Git, and Jenkins should appear naturally in your resume if they reflect your actual experience.

Portfolio quality matters too. Recruiters will pay attention to whether you have meaningful technical projects, not just class assignments. A GitHub repository with clean documentation, tests, and readable code can help your application feel more credible.

Interview Preparation

Example Interview Questions

• Walk through a C++ project where you had to debug a difficult systems-level issue.
• How would you explain the difference between user-space and kernel-space code?
• What happens when a network service needs to manage configuration changes reliably?
• Describe a time you improved performance, stability, or maintainability in a project.

How to Answer

Use the STAR method for behavioral answers: situation, task, action, and result. For technical questions, speak clearly about your reasoning, not just the final answer. Interviewers want to see how you approach ambiguity, how you debug, and how you think about tradeoffs.

When discussing projects, focus on constraints, design choices, and measurable outcomes. If you reduced latency, fixed a crash, or improved reliability, explain exactly how you did it and what changed afterward.

What Recruiters Evaluate

Recruiters are typically looking for technical foundation, learning speed, and evidence that you can function inside a real engineering team. For this role, they also want signs that you understand systems complexity and are comfortable working close to the operating system and network stack.

They will likely value initiative, code quality, and consistency more than flashy buzzwords. If your resume shows that you build, test, and iterate thoughtfully, you will already be ahead of many applicants.

How to Get Selected

Practical Tips

• Tailor your resume to systems programming and networking, not generic software development.
• Highlight C++, Linux, debugging, and infrastructure work first.
• Show at least one project with measurable technical depth.
• Prepare to explain low-level concepts in plain English.
• Practice reading unfamiliar code quickly and accurately.

Common Mistakes to Avoid

• Submitting a resume that looks broad but shallow.
• Listing tools you cannot discuss confidently in an interview.
• Ignoring Linux, networking, or memory-management fundamentals.
• Talking only about coursework without showing applied work.
• Giving vague answers about bugs, tradeoffs, or design decisions.

How to Stand Out

The best way to stand out is to show genuine systems interest. Build a small but polished project in C++ or Python that touches networking, concurrency, or Linux tooling, then document it clearly. Even a compact project can be powerful if it shows clean engineering habits.

Networking with current or former employees can also help, especially if you ask informed questions about the Platform team, mentorship structure, or the Arista Prep program. A tailored application that mirrors the company’s focus on performance, reliability, and collaboration is more persuasive than a generic one.
