I have worked as CTO and some other leadership positions and done my handful of interviews. In those cases, I have always tried to strike a conversation with the person, see what he likes about the software world and try to make him feel at ease (taking into account that it is an interview). If the person is especially anxious, going out to have a friendly coffee works too because it's a more neutral ground.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
