First, I had to complete a short survey about my skills and experience, as well as a small coding sample. I was given one hour to complete the coding sample.

There were two questions, with the first being relatively simple and the second being a bit more challenging. I managed to do well enough to get a phone interview where I was asked to program solutions to a few problems.

Unfortunately, I was not able to advance to the next interview stage.

Increment a positive integer that is represented as an array of characters (e.g., increment ['1', '2', '3'] to ['1', '2', '4']).

Add two positive integers that are represented as an array of characters.
