One of the founders send a message to https://gophers.slack.com so I messaged him about the position.
I shared my CV, and my experience so I moved to the tech interview.
During the tech interview, the same founder and an engineer were asking me questions about my background and how I implemented some of it.
In the end, they asked how to implement something in Golang.
During the interview, they said they liked it a lot and that they would talk and get back to me, but I got no answer.
A week later I sent an email asking for feedback and never got an answer.
