THERE is a time and place for a flanny (coupled with some body odour), but it's definitely not the interview room.
Every day employers are astonished by the varying walks of life that stroll, and sometimes drunkenly stumble, through their doors to apply for a job.
So, when is that spaghetti-stained T-shirt just a few days past its wash date?
One Warwick business manager suggested if you had to question the cleanliness or appropriateness of your interview attire, it was probably worth changing your view.
"Poor presentation and hygiene are a few basic ones," he said.
"We realise some people come straight from a worksite to an interview and sometimes we can forgive that but, for the people who haven't, there isn't much of an excuse."
It's not just one's presentation that can prevent an employer hiring you.
The way you communicate, and what information you choose to divulge, can also land you in strife.
"You see them at both ends of the scale. Some say very little and you have to drag the information out of them, or some volunteer too much information," the manager said.
He said bad-mouthing past employers was also a no-no, as it showed immaturity and unprofessionalism.
Compulsive foot-tappers be warned: fidgeting also made it onto the top What Not To Do in a Job Interview list, with this one a pet hate among many employers.
"It shows they haven't got time to be there and makes you feel as though you're taking up their time," the manager said.
If you're guilty of any of them, it may be time to change your game plan. While you're at it, consider the following tips from MyCareer.com.
"The first 30 seconds count. Whether it's a date or a job interview, our brains make snap judgments about people within seconds of meeting them, and it starts before they even open their mouths," Lisa McLeod writes.
The handy jobs website states open body language and smiling are also key components to nailing an interview.
"Before you walk in the door take a minute to take a deep breath, relax your shoulders and straighten your posture.
"If you walk into the room with open body language you'll come across as confident and relaxed."
MyCareer suggests being enthusiastic about your interview, but don't suck up.
Authenticity is also key.
So next time you slap on a flannelette shirt for a job interview, or turn up with no idea of the job at hand, take a second to consider your other options.
Remember, first impressions last.
