Testing Your Knowledge and Experience
Make sure what you can live up to your claims in your résumé and cover letter, because your interviewer may try to test your knowledge and experience.
For example, they might ask you questions in your field or get your professional opinion on some current events happening in your expertise. Another way to test your knowledge is to walk you through a sample scenario you might face in this new job, and ask you how you would solve the issue.
The best way to prepare for these questions is to read up as much as you can about the industry that you're applying to, and brush up on items in your past. Give yourself time to think about how you would tackle the problem they present to you, and don't rush your explanation. Even if you don't arrive at the conclusion the hiring manager is looking for, they may be impressed by your thought process.
