Analyze the Job Description

Any interview is definitely a one time make or break. The company will make a decision on you as a candidate for the role you are interviewing for, but they will also decide how they feel about you as a candidate for the company overall. 

Knowing what you are interviewing for is more than just knowing the job title and position basics. It means dissecting the job description and knowing how to apply your past experience to the job being filled.

For the anatomy of a job description, there are usually 4 main parts: the overview, the responsibilities, the requirements, and the desired attributes.
