I went through the process about 2 months ago, and I really enjoyed it.
After the initial quiz, I had a ~2 hours interview with a human, which included a 1h "pair programming" challenge, random technical questions on my field, general CS questions and architecture (system design) type of questions.
Once I passed that step, my talent manager (the person who helps facilitating the discussion with the companies) told me IIRC that about 1 in 5 passes the human test.
Based on my skill set and preferences, the system "offered" some 30-something companies, and I chose to have an introductory call with ~10 of them. Each company has some background information, what they're good for (in TripleByte's opinion), their general size and their engineering size. Some companies (the bigger names) have additional steps before the on-site, like another pair-programming session or take-home exercises.
From those calls, 5 on-site interviews stemmed, and 4 of those resulted in an offer.
TripleByte also helped arranging the on-site all in the same week, so if you're remote you don't have to fly back and forth all the time.
Of course the comparison between Karma and Mocha is weird, that's why the entire Karma/Jasmine/Phantom combo and Mocha/jsdom is mentioned.
There's one piece missing in the Mocha/jsdom combo actually, the assertion library, and we use `unexpected` for that purpose.
As you can see from the article, this is not truly a comparison between Karma and Mocha, but I wanted the title to be intentionally provocative, to sparkle some discussion around the topic :)
We use test-automation for real browser testing but prefer to rely on quick and functional unit-testing, thus the choice to go with jsdom.
Regarding the community, you're right, there's a `karma-something` for every need.
However, mocha is pretty popular too, and getting momentum by the day. Also the fact that it simply runs on Node makes it quite easy to obtain what you want without extra plugins (e.g. coverage).

Top notch service, imo
