I had a technical phone interview, followed by a 4-hour in-office interview, and then a 1-hour interview with some upper management.

The phone interview was pretty typical. I was asked some general, basic black-box testing questions.

The 4-hour in-person interview was a bit more technical. Since I have some coding experience, they asked me to write a function that would take a random array of integers and see if the sum of two integers was equal to another value passed in (i.e., public bool findSum(int[] array, int sum)). The person asking this question definitely wanted me to consider performance. I answered this question well, in my opinion.

The last interview with the VPs didn't go so great. They asked me a couple of tough questions for which I didn't have great answers (i.e., if I were testing a piece of software that lived on top of a database, what extra test cases I would come up with for different languages). I came up with tests for every new character (FYI, the Chinese alphabet has thousands of characters) and a few other tests, but I definitely think they were looking for something specific that I didn't come up with.

Find the sum in an array.

(i.e., public bool findSum(int[] array, int sum))
