Like a video/phone call?

Indeed, a request for a short video call filters out most of the people who are looking to pad their resume with LLM-automated contributions, while adding an extra layer of welcome to genuine newbies who want to join the community.

I'm not sure if AI can do those today, but they probably can in the near future. (probably we will be able to see obvious "that can't be human" for a while longer)
