I applied online. The process took 1 week. I interviewed at Arista Networks
Interview
1st round - Leetcode type coding test on putty. The server was in US, and I'm typing from Sydney. So lots of lag. Anyway cleared it. In this day and age where there are very good online code collaboration tools, not sure why they are going with putty.
2nd round - Asked about a multithreading scenario. Answered around 80% of it correctly. Same problem with putty again.
3rd round - Started off innocently with STLs. Then the interviewer started deep diving into unordered_set implementation and asked me to code it up. At one point of time to answer the interviewer's subquestion - I told to make an assumption that a pointer is 4 bytes. He started laughing. I didn't have much hope after that and predictably the interview went south from there.
Interview questions [1]
Question 1
Remove all nodes with a value N.
A multi-threading scenario question.
Unordered_set implementation
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.
