About Our Interview Questions

Our interview questions are created by writers, almost all of which, have a long history of recruiting and interviewing candidates. They do not necessarily have experience interviewing or working with companies, careers, or schools, in which they may write for on MockQuestions.com. We do, however, strive to match their background and expertise with the appropriate question sets found on our website.

Our careers, companies, industries, and schools may have duplicate interview questions and answers found elsewhere on our website. Specifically, our companies and our graduate school interviews. For these two, we use the industry in which we believe the company most well-represents and the graduate programs, as the basis for the interview questions and answers that generate for each company or school.

The intent of MockQuestions.com is for our users to build confidence for their job interview, by using our thousands of interview questions and answers as they practice and prepare for their interview. We believe, most of our visitors can become more likely to succeed in their job interview with hard-work and practice. We believe, the key to success is for our users to rehearse with our interview questions while using our answer examples as an idea generator for their own interview answers. We strongly want to discourage users from memorizing our answer examples. That is not the purpose of our website.
