Entrevista
I had the interview with Expedia for HotWire Division there via GSPann.
I had 3 rounds of interviews -
Round1 : Zoom video call to write the code for the given problem.
Round2 : Zoom call to discuss on few problems to know the approach I will take.
Round3 : Zoom video call with Senior Manager for technical discussion.
Though they say that they will take all 3 rounds to decide & to have fairness, but God knows about the fact.
