I participated in two phone interviews. I did not clear the second phone interview, so I can't speak for the rest of the interview process.

Each phone interview was accompanied by a Google Doc where you typed in your code.

In the first phone interview:

• I was asked to give an introduction of myself.
• The interviewer asked me two technical questions.

In the second phone interview, I was asked two technical questions.

In three of the four questions, I was asked to walk them through some test cases after writing the code.

Implement a class that can calculate the running average of a stream of input numbers up to a maximum of N numbers.

Implement string rotateString(string input, int amt).

Implement int strncmp(const char* s1, const char* s2, int n).

Implement a function that takes the set-wise subtraction of two sorted sets of integers. For example:

A = {1, 2, 3}, B = {3, 4, 5} => A - B = {1, 2}.

There can be duplicates. If duplicates exist, all duplicates should be removed if there is an occurrence in B. For example:

{1, 2, 3, 3, 3} - {2, 3} = {1}.
