Me postulé a través de una facultad o universidad. Acudí a una entrevista en Arista Networks (Bengaluru) en ago 2024
Entrevista
OA Round
There were 4 Sections -
20 minutes for 15 MCQs.
20 minutes: Integer To Roman
25 minutes: In a grid(m*n) with obstacles, find if (m-1,n-1) can be reached from (0,0) in less than or equal to a given time where each movement costs 1 unit of time.
25 minutes: Given an array of binary strings (like "1101" representing 13) and a maximum 'k' number of operations that can be performed. The operation is taking the 1s complement of a string. Find and return the maximum possible sum of all the strings.
There were 2 Rounds both technical.

Pros:
Great initial approach – the recruiter thoroughly checked my GitHub profile and projects before the interview, which is very uncommon and shows they do their homework.
Cons:
A major mismatch between the job description ("Software Engineer C++") and the actual interview reality. The technical stage on CoderPad strictly tests bare-metal C98 skills: raw pointers, manual bitwise operations, and packing bytes into 64-bit integers. If you are accustomed to modern C++ (RAII, templates, safe memory management), this will feel like a massive step backward. Additionally, the time expectations for live low-level bit-shifting were unrealistic, to the point where the interviewer started solving the task themselves.
Interview was kind and not stressful, just minor mismatch of naming

Pretty good, not too complicated, was comfortable. Mostly LC questions, and was easy enough that you should be able to do it after doing NC150. good luck for the interview!
Starts with online test, then three rounds of technical interviews follow.
Not a lot of discussion, just go straight to the technical challenges which have to be solved in time
