Real, anonymous reports from people who interviewed for Software Engineer at Arista Networks, newest first and distilled into what to expect across the loop.
After a recruiter touchpoint, I ended up in a first technical round that was very data-structures focused. The environment was a coding platform where I had to write out everything, including the driver/boilerplate, and the problems were mostly rooted in linked lists and trees. The interviewer was fairly relaxed, and the hour flew by.
The process felt pretty direct once I got in the door. I had about an hour of interviews total, mixing behavioral questions with technical questions drawn from my resume, and then a LeetCode-style coding problem. The setup had a few interviewers who took turns asking questions, so the conversation moved around rather than staying with a single person.
Candidates can expect a technical coding interview focused on data structures and algorithms, particularly linked lists and trees, often in a LeetCode-style format. Interviewers emphasize not just code correctness but also memory utilization and pointer behavior during problem-solving.
Some candidates report a hands-on technical interview experience where they connect to a server or coding platform to solve problems in a real-time environment, which mirrors actual engineering tasks more closely than traditional whiteboard coding.
The interview process typically includes a behavioral or cultural fit round, focusing on the candidate's background, past experiences, and alignment with the company's values. This round is often conversational and less technical.
Candidates have noted that the overall interview timeline can be slow, with delays in scheduling and communication from HR. Some experienced a lack of proactive updates, leading to frustration during the waiting period.
In later technical rounds, candidates may face questions that require them to discuss time and space complexity, as well as optimization strategies for their solutions, indicating a strong emphasis on algorithmic efficiency.
While many candidates received offers, some expressed disappointment due to long wait times for feedback or rejections after what felt like solid performances. The overall tone of the interviews was generally positive, but the lack of closure was noted.
