If the interviewer knows what they are doing, you will be asked if you have any questions about the job. Be prepared! Asking good questions shows that you are interested and prepared. The answers to those questions should also help you decide whether or not you want to work for the employer.
Employers usually have several candidates for every job, and they aren't interested in a candidate who isn't really interested in them or the opportunity. Typically, a job seeker with no questions is assumed to be either not really interested or not very bright.
Questions to Ask in a Job Interview
Try not to ask questions that can be answered with a simple yes or no.
You want more information, and people will usually provide that if you ask "open-ended" questions, like these below.
