After applying online, I received an email approximately two weeks later asking me to schedule a phone interview.

This first interview was straightforward. I was asked a few basic technical questions, including the time complexities of various sorting algorithms.

I was then asked to schedule a phone screen. The interviewer gave me a problem to solve over the phone, and I was to solve it on a shared Google Doc.

I apparently did not do so well, because I was not allowed to proceed to the next phase. However, I did receive an email letting me know that I would not be considered for further evaluation.

Which is faster, bubble sort or quicksort?
