Applied on LinkedIn. Was contacted back within a couple of days and had a video call interview with the founder to discuss the specifics of the role and tell a bit about myself, no technical questions asked.
After a few days had another video call set up with two people, founder and also one of the developers. Overall the chat went well, but the developer didn't really prepare/had that many questions and was doing other stuff during the call, so most of the questions were asked by me. At the end of the chat, they said that they didn't know what was the next step. And after this, I never heard back.
