Suppose as part of the interview process you’re given a programming assignment to see how well you write code. Suppose you’re tasked with writing a custom string class and you’re asked to implement a few methods: indexof, containscharacter, insert. Suppose you’re also explicitly told that you’re not allowed to use the native string type as your internal storage, which would naturally lead to using a char[].

Is it reasonable to assume you’re expected to implement those methods working against your character array, or am I wrong for thinking you’re retarded if you just do return(charArray.ToString().indexof(charToFind))?

Additional info: you’re given several days to complete this.
