They sent me an email for initial contact after I had already applied and interviewed.

We had a brief phone call, and then they sent me a link to a programming assessment.

This assessment asked two very involved problems to solve in their homemade IDE within an hour.

It seemed impossible for any normal person to complete within that timeframe.

I solved the first problem but ran out of time on the second.

Subsequently, they sent me an email stating they wanted to personally call me with the results, only to inform me of my rejection.

One question was strange: it involved taking specific digits out of a large number and adding the rest together. The other question was stranger still, about looking through a directory, except the directory was a single string.
