Some employers, particularly those in the consulting industry, use a method of interviewing called "case interviewing." Case interviews are used to assess how well you can dissect a problem, utilize your relational skills, and apply your creativity. Your challenge is to strategize a solution to a problem. Your responses must display your listening skills, analytical skills, interpretive skills, ability to focus on actions and results, presentation and communication skills, and personal attributes.
As case interviewing is a unique style of interviewing that requires an understanding of the technique, many employers will let you know if they have a case-based interviewing process in advance of the interview.
Practice, practice, practice. Go to Thayer or Dartmouth Career Services for access to the books on case interviewing. Approach the sample cases in these books as if you were in an actual interview for a job you really wanted.
Bring a pen and small notebook if you wish to sketch a scenario or perform mathematical calculations.
Ask clarifying questions before you begin and, if necessary, as you go along.
Take time to think through your essential points and to organize your response. Do pause and mentally regroup as needed.
In all cases, restate the problem, make certain assumptions, identify needed research and analysis, summarize and make a recommendation
