This would be a totally unsuitable format for this task. When doing this task, most of the time is spent looking at the code and reading what is already there. The actual changes needed are very minimal. It is explicitly not about complicated logic flow or algorithms like most interviews, but rather about a software engineering process and the ability to discover things yourself.

Also, the actual time limit (the real author of the question showed up in this thread) was 1 hour. I'd say in actuality it's roughly a 30 minute process.
