Recently had the phone screen round for Google L3 position India
was asked only 1 Graph BFS question.

first the interviewer asked me to give the approach for this medium level BFS question , after i finished explaining the approach he gave another followup question to this same problem and this follow up was of hard difficulty.Was able to explain the approach for the hard level followup and code it within time.

passed the screening round, pls wish me best of luck for the next rounds
