An interview with someone in a particular kind of job so you can learn about that job. For instance, if you are thinking about being an architect, you would interview an architect to find out what it is like.
The "opposite" of a job interview, in which you interview an individual (a target) whose name you obtained through a credible intermediary. The target works at a job or career that you think you might like to know more about before you decide to pursue this potential career direction. Ideally, you'd like the target to tell you: how she got the job; what she likes and doesn't like about the job; who else does similar work whom you could contact.
A job search strategy that involves arranging a meeting with a potential employer and telling them that you are interested in learning more about the company and that you are interested in that particular kind of work. The purpose of this is to increase your networking contacts. Hopefully sometime in the future, the employer will remember you when a position becomes available.
