An On Demand interview is an interview you complete through HireVue at your convenience. When you start the interview, you will have the option to take practice questions to become familiar with the system prior to answering your real interview questions.
Most interview questions will require a video recorded response. You may be asked to write an essay response or answer multiple choice or multiple selection questions. On Demand interviews are set up and managed by the company you applied to. Just like an in-person interview, you will not know the questions until you start the interview.
