Many HR representatives and entrepreneurs dislike the candidate selection process. What worries them the most is when after going through all the resumes and choosing a good candidate, the candidate turns down the position. Believe it or not, this scenario happens very often. Also, giving the job to the wrong person is another disastrous scenario.

To help you avoid these problems, here are 8 science-backed ways to help you with the interviews:

Appearance Distraction

While at the interview, the first thing that you should be doing is to take a serious look at the candidate and see if your first impulse is rejection. You may not be aware of this but scientific studies have shown that the physical appearance of a candidate plays a big role in the selection process. If you do this, you could be rejecting your newest standout employee just because he or she has a small scar for example.

Body Language

Most hiring decisions are based on what a person is not saying rather than what is coming out from his or her mouth. The bad thing about this is that you could be making assumptions based on lack of eye contact or poor posture. During the interview process, make sure that you are evaluating the applicant's body language correctly.

Stop Dragging

Don’t wait too long to hire your best candidate. Source: Mashable

According to DHI-DFH Mean Vacancy Duration, the average job vacancy duration is 26.1 days. While you may know that searching for the perfect candidate takes time, what you may not know is that waiting too long may mean losing your best candidate to a competitor.

Just Talking Is Not Enough

Unstructured interviews could interfere with the interviewer's ability to properly assess the candidate. Instead, you should do a structured interview and ask specific duties or questions that the candidate may be responsible for if he or she is hired for the job. The answer is then measured against a scale of some sort.

Work Samples

Getting more work samples is a better indicator of future performance compared to not getting enough work samples.

Wrong Social Media

HR departments or entrepreneurs seem to misfire when it comes to looking for candidates when using social media. According to the statistics, 92% of businesses post on Twitter but 51% of the people on Twitter are not looking for a job. Most job seekers use LinkedIn, but only 23% of businesses are posting there.

Dig Deep

If you are not using social media networking to evaluate a candidate, then you are in the minority. A study in 2015 revealed that 52% of employers dig through social media to know more about the candidate. And the number has only been growing since then.

Company Culture

Employees that fit well with the company culture have higher productivity and work satisfaction levels. Hence, it's essential that you don't misrepresent your company’s culture. For example, if you are in a company that prefers a casual and laid back attitude, then don't do the interview wearing a business suit.
