The first job in your life can mean a great lot and has the potential to either make or break your career. In legal jobs, this is truer than in other work arenas because lawyers are a closely-nit community characterized by intense social networking.
The "where" has to do with more than simple geography. It may include the types of knowledge one would expect to use in the job hunt, the people internal to the organization and those served by it, as well as the everyday working conditions. "Where" would also include the level or salary you would expect if you worked in this particular organization.
When you are fielding questions at a legal job interview your answers must be direct and to the point, as short as is humanly possible, and must end either in your silence or in a question for the interviewer which may or may not be related to the question he asked you. Remember that your objective in a legal job interview is to keep the interviewer talking as much as possible; keep the ball in his court!
