I applied through an employee referral. The process took 1 day. I interviewed at Arista Networks (Burnaby, BC) in Jun 2013
Interview
I'll keep this in bullet form to be brief:
• Implement a stack in your favorite language (I used C++)
• How are arguments passed in C? (Where? What order?)
• How does virtual memory work? Went into some detail on what happens on Linux when a page fault occurs.
• How would you get the address of a field in a C struct?
• Write a method to find the in order successor in a binary tree.
• Debug this method in GDB.
• What is the Big O complexity of this code?
• Other computer science questions I can't recall.
Essentially, you should know stacks, trees, heaps and other data structures, as well as basic sorting, searching and optimization algorithms.
Interview questions [1]
Question 1
How are programs and data typically organized in memory? Draw a diagram. (i.e., DATA, BSS, heap, stack)? I hadn't thought about this for a while, but I still got 90% of the answer correct.
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
