Codility (online programming test) assessment + phone interview.

The question was easy enough, but it was horrible trying to write production code in a Google Doc in 5-10 minutes.

He went through all the corner cases, such as an empty string, and kept poking holes in my code.

Fair is fair, and I never thought it would be easy. I am pretty sure I won't make it to the next round, although I didn't get the result.

First, they sent a coding assessment on Codility which had two questions.

One was to return the number formed by interleaving the decimal digits of two numbers.

Then, during the phone interview, I was asked to serialize and deserialize a vector of strings in C++.
