Candidate Information: B.Tech 3rd Year Student Fresher (Internship) Bangalore/Chennai/Pune August 2025 Overview of Interview Process: The process consisted of an OA conducted in college labs followed by two technical interview rounds conducted virtually via Google Meet. The focus was heavily on DSA & CS Fundamentals. OA Online (HackerRank) 15 MCQs - C/C++ Pointers, OOPS, Aptitude Given an array and integer k, find the max sum of a subarray of size k where all elements are distinct. Similar to LeetCode 2462. Technical Interview 1 Google meet (CnP Office) C pointers What does ls | grep do? Rearrange a linked list a -> b -> c -> d -> e ... such that a < b > c < d > e ... (you have to tell the linear time complexity solution) CS Fundamentals - OS, CO Technical Interview 2 Google meet (CnP office) Deep dive into my project (scene text recognition in bad weather) Discussed my contribution in project Questioned on technical challenges and optimizations What is object slicing How do virtual functions work at the compiler level LLD question The interviewers we helpful and provided hints when I got stuck. They want to know your thought process. Tips: You shall know core fundamentals in details. How things work on compiler-level rather than just coding. Master OS/CO concepts and have a clear, in-depth explanation prepared for your resume projects.

About Arista Networks Interview Reports
This question was reported by a candidate who interviewed at Arista Networks. LeakCode aggregates interview reports from 10+ sources, including 1Point3Acres, Glassdoor, LeetCode Discuss, Blind, Reddit, Indeed, and Nowcoder. Each report is translated where necessary, deduplicated against existing entries, and tagged by company, role, round type, and reporting date.
Use this question as one calibration data point, not a memorization target. Companies typically rotate their question pools every 2-4 months; the exact wording of a 2024 question may differ from what you encounter today. The underlying pattern, difficulty level, and follow-up depth at Arista Networks are the higher-signal extractions to take from this report.
For broader preparation context, the Arista Networks interview process typically includes a recruiter screen, one or two technical phone screens, and a 4-5 round on-site loop covering coding, system design (at L4+ levels), and behavioral. Reports tagged on LeakCode show the round-by-round distribution and typical difficulty calibration. To browse questions filtered by round type and seniority, use the company hub linked above.
How To Practice This Type of Question
Solve similar problems on LeetCode under timed conditions (25-35 minutes per medium difficulty). The goal is pattern recognition: recognize the underlying technique (sliding window, two-pointer, BFS, memoized recursion, etc.) within 60-90 seconds of reading. Strong candidates verbalize their hypothesis out loud before coding, then iterate based on feedback. Weak candidates dive into implementation immediately, lose time on the wrong approach, and run out of time for follow-ups.
Companies update their question pools every 2-4 months. The exact wording of any given question may have been retired by the time you interview. Focus your prep on the pattern, not the specific problem. The patterns that appear in Arista Networks reports consistently are the ones worth investing in; one-off niche problems are not.
During Your Arista Networks Round
Apply the standard interview round template: clarify requirements (2-3 minutes), state your approach out loud and confirm direction with the interviewer (3-5 minutes), code with narration (15-25 minutes), test with concrete examples including edge cases (5 minutes), discuss optimization or trade-offs if time permits (5 minutes). This template is universally accepted across FAANG and adjacent companies; deviating from it produces weaker interviewer feedback signal.
The single most predictive failure mode in Arista Networks reports tagged "no hire": not asking clarifying questions. Interviewers are explicitly trained to weight this. Strong candidates ask 3-5 clarifying questions even on problems that look obvious; weak candidates dive into code immediately. The clarifying-question check is often the first signal recorded in the interviewer's written notes.
