Which of the following is a difference between structured interviews and unstructured interviews?

In structured interviews, interviewers prepare standardized interview questions ahead of time, whereas in unstructured interviews, interviewers are free to ask applicants anything they want.

In structured interviews, interviewers often disagree about which questions should be asked, whereas in unstructured interviews, interviewers strongly agree that the same questions must be asked to all applicants.

In structured interviews, it is difficult for employers to compare applicants, whereas in unstructured interviews, employers can easily compare applicants since all applicants are asked the same questions.

In structured interviews, interviewers tend to ask applicants personal questions, whereas in unstructured interviews, interviewers ask only for important, job$-$related information.
