Interviewing someone for a job is not as easy as it looks. First, as the interviewer, you’re tasked with finding the person who will not only do the job well but also fit in well with the other employees.

You have to make an evaluation of abstract qualities that can’t be found on a résumé. Because you have to repeat the process for every potential employee, you end up asking question after question, applicant after applicant.

Still, interviewers need to be told something: “What is your biggest weakness?” is not a good question. It just isn’t.
