Here are the most commonly searched roles for interview reports -
I contacted a recruiter by email and I got a call for a phone interview within a few days. During the phone interview, the interviewer made me do SSH into their system. He asked me a question on removing nodes in a linked list having a particular integer data value.
He had some code ready and I had to write the code for the function RemoveNode and compile and run it. I messed it up with some logical errors which led to Segmentation Fault. The interviewer wasn't helpful and would sometimes not respond at all when asked something by me.
Then he asked a vague question about how will you debug the code when a customer may complain about the system not working. I gave some answer but then he decided to end the interview. He said I need more practice and would like if I reapply when I am ready. So in short it was a reject at the end of the call itself.

Question 1
Remove nodes in a linked list having a particular integer data value.
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 applied through a recruiter. I interviewed at Arista Networks (Łódź, Lódz) in Jun 2026
Interview
Reached round 3 out of 4 planned, one was coding task, two live coding sessions. Linux development background was highly expected. Performance optimized approach was tested, specially oriented for hardware with lots of resources. I had a problem to properly understand reqruiting person during round 3, voice was not clear for me.

Question 1
List implementation, bits counting, tre traversal.
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!
