Interview questions [1]
Question 1
Create a design to transfer several large files from a server machine to a client machine. The client machine already contains older versions of some of the files that need to be transferred.
Transmitting data between the server and the client machine is very expensive, so the design needs to be optimized for the amount of data sent over the wire.
Online interview round.
There would be 4 interview rounds total. Each one evaluate various skills about you. They will give you hints as well at time required, you need to capture those and rethink on your solution.
