The process took 1 week. I interviewed at Arista Networks in Mar 2012
Interview
Interview is pretty straightforward C questions. WIth some OS kernel knowledges.
Onsite is kinda irregular. only one round one person then meet the CEO.
Interview questions [2]
Question 1
delete all the nodes in a linked list with a specific value
onsite question is: design a stack used by multiple users. Any datatype could be pushed into the stack including self defined struct. only In C. How to do error handling in C compared to C++. How to handle memory leak if the stack method failed.
I applied through a recruiter. I interviewed at Arista Networks in Jun 2026
Interview
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
