"As a senior business analyst, you are being hired for your years as a business analyst, providing you with the experience and guidance that other business analysts need. Interviewers want to see that you are capable of taking on more complex projects by testing your Excel skills, ability to perform an analysis, and leadership in a team setting. Be prepared to focus on your previous experiences with data, multi-tasking, and organizations and how it has all culminated to help you make sound decisions for the company."
You've done a lot of contract work, why should I hire you? I suspect you do not have what it takes to make it here.
