I applied through a recruiter. I interviewed at Help.com (Austin, TX) in July 2017
Interview
A couple of lengthy phone screening calls led to an invitation to complete their online code 'challenge' and post it to github for them to review.
It seemed intentionally vague. Attempt to log on to a raw socket on their server, stream in and parse ambiguous data from it. Handle everything it could throw at you as per random disconnections and bad formats. In the midst of this, be able to submit some queries and show the correct results. Pretty unusual, but I came up with what seemed like a good working application that met the fuzzy requirements as best I could tell.
Rejected for amazingly trivial reasons. Something weird going on over there.
