I went for an interview as a MS SQL DBA. They gave me a technical knowledge test which I passed then started asking about me, All was going well until they started telling me what the company did.

They harvested people's data from websites online questionnaires and collated it into saleable data.

This was too much for me and I'm not certain that it isn't a grey area legally. They were told that they were scum of the earth and they could go fuck themselves.
