Toxic people defy logic. Some are blissfully unaware of the negative impact that they have on those around them, and others seem to derive satisfaction from creating chaos and pushing other people’s buttons. Either way, they create unnecessary complexity, strife, and worst of all stress.

Studies have long shown that stress can have a lasting, negative impact on the brain. Exposure to even a few days of stress compromises the effectiveness of neurons in the hippocampus—an important brain area responsible for reasoning and memory. Weeks of stress cause reversible damage to neuronal dendrites (the small “arms” that brain cells use to communicate with each other), and months of stress can permanently destroy neurons. Stress is a formidable threat to your success—when stress gets out of control, your brain and your performance suffer.

Do you ever feel that business life can be hostile? Maybe you have a boss that doesn’t appreciate you. Or a client that treats you like dirt.

No matter what your place is on the career ladder, I bet you’ve felt misunderstood somewhere in your career. Every day people feel left out, unappreciated, and mistreated at work. And consequently, they suffer.

Let’s face it. Business is not always fun. And sure, it’s business.

But I think we can easily improve the business landscape by getting better at one thing: Emotional Intelligence.

It’s easy to spot a good candidate – just take a look at their skills and professional experience. Now, to find a great candidate, that is another story.

Finding top talent is a bit more complicated than perusing through a CV, because the best employees not only have the required technical skills, but emotional skills as well.

In fact, the World Economic Forum’s Future of Jobs report noted that emotional intelligence (EQ) will be among the top ten most wanted employee skills by 2020. Employees will have to develop skills like emotional intelligence in order to compete in the advent of artificial intelligence (AI) and the ever-changing workforce.

But how do you screen candidates for emotional intelligence? It’s a bit more tricky than testing a candidate’s writing skills. Here are four suggestions to help recruiters know if a candidate has high emotional intelligence.
