I applied through a recruiter. I interviewed at Arista Networks (Bengaluru) in Oct 2016
Interview
They have 3 rounds of interview. The candidate would move to the next round based on the feedback of the previous round. They mostly look for exact solution and code for the same
1. Coding round
2. Algorithms round
3. Director interview (Design)
I could not get through the first round
Interview questions [1]
Question 1
1. Given an unsorted array, find all possible pairs which sum to to a given number with log(n) complexity
2. Given an array of strings, find all possible possible concatenations of strings. e.g., for a, b, c, d output should be ab, ac, ad, bc, bd, cd, abc, abd, bcd
3. Design a stack which will do push, pop and min element in O(1) time
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
I interviewed at Arista Networks (Warsaw, Masovia)
Interview
By now I have had only first interview, that was focused on pure DSA. Despite that I would already recommend checking out gdb, cause it came in handy in my case.
