The interview process began with an initial phone screen with the recruiter, followed by a technical Google Hangout.

The interviewee was pleasant, but I felt they became disinterested early on.

I had some initial difficulty with the problem, but was able to complete the majority of the requested features. However, during the process, the interviewee attempted to help with my solution and got it somewhat working. Upon reviewing the code prior to the interview, I realized what the interviewee wrote actually introduced more bugs.

My initial approach was correct, and I'm unsure how this might have affected the outcome of my interview and overall experience.

Build a progress bar, then make three progress bars run in series.

Then make five progress bars, but two of them start staggered. When one completes, start the next progress bar in series.
