I focus on all aspects of an interview for case prep. I believe there are three key aspects to an interview that help crack an interview: the ability to structure and break down the problem.

Communication skills are the next key ingredient- ability to keep the interviewer engaged and passing the 'airport' test and finally getting the analytics right with a dash of creativity in proposing solutions.
