Job Interviews: 101 Common Mistakes to Avoid

Business

You have found a great job opportunity. You have the necessary skills and experience. Everything is going according to plan, but for some reason you are not selected. What happened? You may have made a mistake in the interview. Most hiring managers are willing to let one or two small issues slide. However, if you make several of the common interview mistakes, you’ll never make the short list.

We interviewed hiring managers, recruiters, and even job seekers to identify the most common mistakes job seekers make. We intentionally do not rank the list of interview crimes, as their impact will vary widely depending on the attitude of the interviewer. As you go through the list below, some errors will seem pretty obvious, even common sense (and humorous). Some bugs apply only to one genre, but there are plenty for everyone.

We encourage you to review our list and make your own personal checklist, based on the job, the company, and your past experiences. Before each interview, look at the list again. In this way, it will be conditioned in its behavior and responses. After each interview, find out as soon as possible. Review the list, reviewing those items that were mishandled.

By carefully crafting your answers and avoiding interview mistakes, your confidence will increase and your job campaign will improve dramatically.
