Caesar's Cipher

Named after Julius Caesar, Caesar’s Cipher is one of the earliest known and simplest ciphers. It is a type of substitution cipher, in which each letter in the plaintext is 'shifted' a certain number of places down the alphabet. For example, with a shift of 1, A would be replaced by B, B would become C, and so on:

plaintext: defend the east wall of the castle
ciphertext: efgfoe uif fbtu xbmm pg uif dbtumf

We’re writing a method that takes a string - the text to be encrypted, and an integer - the rotation factor, and returns a string with Caesar’s Cipher applied.

This is so wack. How are you supposed to know how to answer this in an interview ?
