The process took 1 week. I interviewed at Arista Networks in Mar 2012
Interview
Interview is pretty straightforward C questions. WIth some OS kernel knowledges.
Onsite is kinda irregular. only one round one person then meet the CEO.
Interview questions [2]
Question 1
delete all the nodes in a linked list with a specific value
onsite question is: design a stack used by multiple users. Any datatype could be pushed into the stack including self defined struct. only In C. How to do error handling in C compared to C++. How to handle memory leak if the stack method failed.
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.
