Arista Networks software engineer interviews reported here are technical and fundamentals-heavy. Candidates describe recruiter or HR conversations followed by technical interviews, although the sequence and number of conversations vary. The recurring preparation theme is writing and explaining low-level code under live-interview conditions.
Software engineer candidates encountered C-focused questions and coding work involving linked lists, binary search trees, strings, stacks, arrays, debugging, and algorithmic problem solving. Reported environments included CoderPad and SSH, while one candidate applying to a C++/C-listed role was unexpectedly asked to use Python. Practice implementing common structures in the language expected for the role, then narrate edge cases and tradeoffs as you work.
Networking knowledge can also be relevant: reports include DHCP, ARP, Ethernet encapsulation, OSPF neighbor states, and packet-flow reasoning. Candidates additionally describe Linux, memory-alignment, and debugging questions. Be ready to connect those fundamentals to your own projects, because resume discussion appeared in both screening and later technical conversations.
Evidence on the exact format is limited and varies by candidate, so treat the stages below as reported patterns rather than a fixed sequence.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report an initial screen that may cover work experience, resume projects, interview structure, or fundamental C knowledge. One reported screen also included printf-behavior questions and a medium coding challenge.
Software engineer candidates report live coding on platforms or terminals, including linked-list manipulation, strings, BST operations, hash-table implementation, and easy-to-medium algorithm questions. Language familiarity may matter in addition to the approach.
Technical conversations may probe C strings, memory alignment, Linux behavior, signals, debugging, or networking concepts such as DHCP, ARP, Ethernet headers, and OSPF. Candidates report being asked to explain underlying behavior in detail.
One candidate reported a technical interview followed by a hiring-manager interview after the screen. Later conversations may combine project discussion with coding or systems fundamentals, rather than following a purely behavioral format.
