Two weeks later I sent a polite email to check in. No reply. Repeat two weeks later.
About two months later I received a reply that said the positions were filled, but that they would love to offer me as a candidate to US companies. This was useless to me as I live in Europe.
I believe the interviewer position was a sham, and they were just eating people's time in order to get detailed developer data.
I actually think everyone aced it and ends up in the 80-100 percentile group. "This site says I know more than 80-100% of users" is good for word of mouth marketing.
