Sure, there are situations in which I believe there should be a certain expectation of privacy. Personal conversations like interviews are one of those situations. If I put something on facebook or linkedin I understand that there is a certain level of privacy I am giving up, it's a tradeoff many of us make for a service. Also, I have control over what I expose about myself on the internet, a recorded conversation that stays with an interviewer is not data I can control. If I have a one on one conversation with another individual or individual(s), I don't feel I should have to worry that what I'm saying is being recorded for analysis later on.
