Asking questions is one of the most important parts of any job interview. It's important to show that you are engaged in the process and interested in the position and the company. However, asking the wrong questions can be just as detrimental as not asking any questions at all. Read on for five questions that will get you crossed off the candidate list.

What Does This Company Do?

You should have done plenty of research on the company before the interview, as well as demonstrated that knowledge to the hiring manager in your answers to their questions. With company websites and materials easily accessible online, there's no excuse for not becoming intimately familiar with the job and the organization before you arrive.

What is your drug testing policy?

Regardless of whether the company has a policy in place, this question is a huge red flag that makes you look immediately unprofessional. There's no reason to ever ask about the drug testing policy in interviews, and doing so will make it easy for companies to remove you from the running.

How long until I can have your job?

While advancement opportunities are an important consideration in any job offer, the interview should be spend expressing how enthused you are about (and how well you can do) the job you're being offered. Appearing to see the position as a stepping stone may make the company wonder how long after they hire you until you jump ship.

What about overtime?

Asking about overtime is a double-edged sword. For one thing, many employers are budget-sensitive, and concerned about hiring an employee that they'll need to pay above and beyond the scheduled hours. In addition, asking this question makes it seem like you don't want to work any more than the bare minimum required.

Any question about what you’ve already been told.

Pay close attention during your interview as well as to any communication sent by the company in preparation for the meeting. Asking the recruitment team to rehash information they've already provided makes you look flaky and unprepared.

Avoiding these red flag questions will increase your chances of getting a second interview--and hopefully, an offer for the job you've always wanted.
