Interviews are intended to be a conversation between you and the person holding the interview. You should be asking just as many questions as the employer so that both of you can walk away from it knowing whether you’re a good fit for the company or not.
When you’re nearing the end of the interview and the employer asks “Do you have any questions for me?” take the opportunity to show that you’ve prepared and you’re just as interested in learning about them. It’s the easiest way to determine whether you’ll be happy working for them and you’ll know if your goals are in line with their goals.
There's another reason you should always prepare questions. Amy Hoover, president of TalentZoo, says "It's expected — and if you don't ask at least two questions, you will appear disinterested, or worse, less intelligent and engaged than a prospective employer would like." It’s best to have at least four questions prepared, though, in case your original two are answered through the course of the interview.
Here are 5 great examples of questions you could ask your employer during an interview.
