The CEO and founder of a successful German company asked me if I was married - as a way to assess my future availability and my readiness to relocate for work.
Another case: I was scheduled a call with the CTO of a well-known German portal, without specifying that half of the call was a technical quiz. I replied nevertheless to the questions asked by the CTO, but I was anxious, of course, because I did not expect it to be already a technical call. At a certain point the CTO says “Sorry, we are not proceeding further”, smiles in an hypocritical way and closes the videocall, before I can even realize what is happening.
Third case worth mentioning: I am contacted by a recruiter on Linkedin for a freelance position in an early stage startup. The startup people apparently did not have much time (or experience) to lead the screenings, so they asked the recruiter to read out loud some technical questions during a videocall. The videocall would be recorded, so they could check how their candidates reply, without having actually to meet them.
The recruiter then confessed me " They want me to ask these technical questions, but honestly I don’t know what they mean". They could see me and judge me, but I could not meet them: I am left with the weird feeling of having applied for a job at Spectre or Freemasonry or some other esoteric entity.
