I was recommended by a friend, so my interview process may differ from others. However, it was fairly standard. I initially had about an hour chat with the CEO and CTO about the product, my past employment, and what I see myself doing. After that I did a take home project (though I had the option to simply send some github code samples)
After that I had a talk with the CTO at a coffee shop about what they would see me doing at the company.
