Any Elixir coding interview tips?

I’m relatively new to the Elixir ecosystem, coming from a Ruby on Rails and JavaScript background, but over the past few months, I’ve built around 8 production-ready demo projects with Phoenix and LiveView systems with real architectural complexity, not just CRUD applications.

One thing I’ve noticed is that the Elixir community seems to value different signals compared to more mainstream ecosystems, so I wanted to ask from an interviewer’s perspective:

When evaluating Elixir candidates, what tends to carry more weight: high-quality personal projects that demonstrate OTP/distributed systems thinking, or meaningful open-source contributions to the ecosystem?

I’m especially interested in understanding what separates someone who simply uses Phoenix from someone companies would consider a strong Elixir engineer.
