We all form first impressions of the people we meet, and they can be permanent. Many of the signals that go into a first impression are nonverbal, and dress and grooming are key among them. In fact, that first 30 seconds can make or break your interview. If the recruiter/hiring manager notices poor grooming instantly, it may be hard to recuperate from that first impression, no matter how good your answers.
Good grooming is an indication to the interviewer that you pay attention to detail, and that you take care of yourself. If you don’t take the time to look after your own basic hygiene or dress appropriately, that sends a signal that you will not try as an employee. The first impression you make on the interviewer is the one you will be making on the company’s clients. Putting little effort into your appearance suggests you don’t really care whether or not you get the job.
When applying/interviewing for a position, whether its light industrial, general labor or office work, it’s always important to maintain yourself hygienically. Showering and dressing in appropriate interview clothing will go much farther than not. You may be underqualified for a position however, if you enter an interview in a respectable, presentable manner this indicates you care, therefore making you more probable to be considered for a job. Keep in mind that this is not limited to strictly hygiene, your posture, eye contact, cell phone distractions and overall demeanor impacts this as well!
Put Simply: Be Presentable!
