I had a chance to talk to someone who worked at Oxide once. I got excited because my experience matches up nicely with their products on several levels.
The person got excited as well and started talking about how to interview there, but the conversation got kind of weird. They kept emphasizing how important it was to not talk about compensation in the interview. Apparently they pay engineers all the same comp (not bad, but would have been a significant step down from every offer I received during that time of my life) and they select for people who aren't interested in getting paid a lot for their unique skills.
Probably not a bad deal for people who like working in that domain with like minded people. At the time I got some very uneasy feelings from being aggressively coached to not bring up compensation or ask any questions about equity during the interview like it was some unspoken rule that would get me disqualified. Maybe the person was exaggerating, but I found at least one other person with a similar story.
Honestly, their comp would have been awesome if I was a single guy living in a low cost of living location and working remote, but at the time it would have meant giving up quite a bit to work for an early stage startup with high expectations and an unspoken rule that I should never ask about compensation.
