I applied online. The process took 4 weeks. I interviewed at Arista Networks (Dublin, Dublin) in Sept 2018
Interview
I have applied on-line for position in Dublin. Interview consisted of four steps:
0. Test on hackerrank.
1. One hour interview with engineer.
2. Two hour interview session with two engineers.
3. Feedback from your colleagues and manager. Candidate should provide contacts.
Interview was average from my point of view, nothing extra-ordinary. Company estimates C and C++ separately. I received offer, but decided to reject it due to salary.
Interview questions [1]
Question 1
1. The first interview. Palindrome and array related tasks.
2. The second interview. Binary search, tree traversing and utility to parse http responses and extract headers from it.
Questions during interview: estimate complexity of implemented solution, data structures, C/C++ related questions.
I applied through a recruiter. I interviewed at Arista Networks (Austin, TX) in Apr 2026
Interview
basics of c printfs. The patterns used in clg days was a bit confusing for a 15 yrs exp person like me. Dont know if its of any use on daily work as a SDE. Then BST programs 30mins 3 programs. Had written 2 and half and its correct for sure. Did ask for 5 extra mins to complete. But was denied.
Keep strong in basics and expect interviewer a SE asian to be strict on time. I thought i would be in for 2nd given i answered most of them. But was rejected.
First round: three medium level questions from Leetcode.
Second round: how to implement a stack with generic elements; how to use gcc to debug.
