      Software Engineer Interview

      4 Apr 2024
      Anonymous interview candidate
      No offer
      Negative experience
      Easy interview

      Application

      I applied through a recruiter. The process took 7 weeks. I interviewed at Arista Networks in Mar 2024

      Interview

      Recruiter invited me to get an online test task. This test is simple, just 2 really easy algorithmic tasks for 1 hour. After this test there should be first interview. Due to a personal reasons I asked to schedule it after 2 weeks and Recruiter I've contacted started to ignore me after that. It took a week or more just to recieve at least one message and it was really hard to finally schedule it. The interview also was easy, there was 2 live-coding tasks with comparing 2 specific strings and another one was to find first missing number in sorted array. The interviewer was friendly and gave some hints. Unfortunately there was some little logical mistakes in the first program, it wasn't permitted to use own compiler and debugger and I unexperienced with using GDB. So I advice to take a look of using GDB if you don't want to repair your program using cout. The interviewer said that it will take 2-3 days to assess my skills and to decide about the second interview. The recruiter should notice me about the results. But after 1 week I wrote to the recruiter asking about the results and it took one more week to get an answer. After rejection I asked the recruiter about some feedback, but after 1.5 week there is still no answer. The recruitment process is standart in common but communication with the recruiter is kinda torture

      Average interview

      Application

      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

      I interviewed at Arista Networks (Vancouver, BC)

      Interview

      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!

      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
