Ho presentato la mia candidatura tramite un selezionatore. La procedura ha richiesto una settimana. Ho sostenuto un colloquio presso Arista Networks nel mese di giu 2011
Colloquio
- Algorithm analysis and design skills need to be current.
- API/Interface design has to be generic to take care of broader conditions.
- They will continue to herd you towards right answers but depending on the experience level, there is an expectation to be in the mould for independent thinking.
- They let u know the outcome of the interview immediately after the f2f.
Domande di colloquio [3]
Domanda 1
Question from an Engineer:
Design API interface for stack. The stack should be able to take as input a wide variety of data types: it could range from byte sized to an n-byte sized structure
Question from Hiring Manager:
1. How is the NULL pointer implemented on a linux system? What is the implication of mapping BSS to the Virtual Memory Segment 0?
Question from Hiring Manager:
2. A snippet of http internet server daemon involving socket(), bind(), listen() followed by while loop (which does accept(), process of http request and close() on the accepted fd). Any subsequent http request from a client is blocked till the erstwhile request is completed. Discuss the reasons as to why the server daemon throughput would get affected assuming that the loop to accept and service the request would get executed in say 10ms in the local machine running the server.
What is the throughput for this server in terms of requests/sec? What are the reasons why the throughput would get affected? Assuming that 1% of the clients cause a 1 sec delay, calculate the throughput.
What is typically the wait till for the socket tcp con block to be removed
( length of inactivity 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

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.
