The interview process had two stages.
First was a video conference with the CEO and the CTO of the company. The atmosphere was relaxed and we talked about my previous experiences. They explained their organisational structure and we discussed my experience with similar structures (agile, remote, code review etc.).
The second part was a coding test a week later. I was given access to their codebase and asked to implement a relatively simple feature. Took me a few hours to complete.
