Re: Free consultancy
I had one like that in the 80s. I worked in the research labs of a big electronics company on RF integrated circuits. I went for an interview with a competitor who had advertised very good salaries. The whole interview was them asking me how I might solve very specific "hypothetical" problems and me giving them enough general information to make it clear that I knew but that if they wanted detail then they'd have to employ me. Eventually I found out that a couple of colleagues had also been interviewed but there never was a job - it was just a fishing trip.
