Question of the day: Why do you want to work in ...?
The most important question in an interview is often the first one: "Why do you want to work in private practice?" or "Why do you want to be a prosecutor?"
Your answer can make or break your candidacy. Should you look like a deer in the headlights, your chance to be an effective and successful candidate will have been sharply curtailed.
Employers are looking for thoughtful answers that show your understanding of what they do. For example, if you are interviewing with a private practice, you should show that you know what kind of clients the firm represents and demonstrate your interest in working for that segment of the market. If you are interviewing with a legal services organization, talking about global solutions to dreadful problems will miss the mark. Unless the office is doing class action work, you will find that most legal services lawyers represent one client at a time.
Know your audience and then hit that question out of the ballpark.
