I met a few people from 21 in Potrero Hill at a coffee stand. When one of them paid, I saw a bitcoin address and it struck up a conversation. I told them I was interested in new things (and bitcoin as well), and they told me that their startup is in stealth and they couldn't divulge any information about it, but could send me a test to see if I had the right skills to continue the process.

It was a multiple-choice test on HackerRank. It was all pretty simple stuff related to general linux/bash/html/sql knowledge tons of questions about bitcoin protocol. Having spent a few hack days in the past on it, i did extremely well and went on to interview with the CEO.

It started to get funny, the CEO would only interview a candidate at 10pm on a Thursday. "pretty busy during the daytime" they said.

Despite the red flag, I did it. We talked about bitcoin for about 40 minutes straight and why I was into it. I got the impression from them that they were onto something really huge, or that they think they are onto something really huge that is going to massively flop. At the end of the call, I asked for any hint into what the product I'm interviewing for does and was told it had to do with hardware.

I feel like I got off the call pretty bewildered.

Glad this cleared things up!
