Telephonic interview first round. they will ask 2 questions in 45 minutes and expectation is to write correct and working code in 45 minutes for both questions. Usually in telephonic interview most of the company will focus on logic, algo and sedo code but here expectation was to write correct code that can be complied in one short. my advice will be to please practice on paper/notepad before interview. anyone trying for facebook, my advice is to practice on paper and not on any idc.
