As anyone who has been in a job search for a while knows, being invited to a job interview is not something easily achieved. Becoming one of the few “job candidates” rather than being part of the usually gigantic crowd of “job applicants” is a major victory.

Unfortunately, too many job candidates blow their interview opportunities, wasting all that time and effort. Don’t be one of those candidates. Never assume that the job offer is “in the bag” simply because you were invited for an interview!

Avoid these common mistakes to land that job

What you do during a job interview is viewed as a “sample” of your work. Everything you do is being judged because they don’t know you (unless you are one of the lucky referred candidates).

Show them you would be a great hire. Don’t make these mistakes:

Mistake #1: Appearing uninterested.

This drives employers crazy. Most employers have more applicants than they need or want.

If you aren’t demonstrably interested in them, they certainly aren’t interested in hiring you.

Instead: Demonstrate your interest in the company and the job. Show up on time, appropriately dressed. Turn off your cell phone.

Mistake #2: Being unprepared.

Obvious lack of preparation is an opportunity crusher. And, lack of preparation usually becomes obvious quickly.

Instead: Be prepared! Preparation will help you demonstrate your interest in them and the job. You will also perform better in the interview when you are prepared.

Mistake #3: Being angry.

Angry people are NOT people employers want to hire. Angry people are not fun to work with. They may frighten co-workers and/or customers or clients. They may also abuse both people and equipment (computers, cars, etc.). Not good contributors to a happy workplace or a prosperous business, even if they don’t “go postal.”

Instead: If you are angry over a job loss, horrible commute to the interview, earlier fight with your kids or spouse, or anything else, dump the anger before the interview, at least temporarily.
