I have been interviewing candidates and observing others interview for my businesses for more than 40 years.
So, setting the stage here, let's assume your company is looking to hire for a certain role and you've selected a few candidates.
Interviewing is both an art and a science. It's also one of the most crucial parts of building an effective business--I talk about the topic at length in my book, All In. And just like anything else in life, you need to practice and refine your skills as an interviewer in order to make the most of your time. Too often, I see managers walk into interviews unprepared and winging it, asking vague questions that don't reveal anything noteworthy about the candidate. What good is an in-person interview if you hear a candidate say the same information already written on his or her résumé?
Here are the five things every hiring manager should do when holding an interview. I've found the following to reveal the most about candidates.
1. Ask all of the candidates the same questions.
You'd be surprised how many managers or even other CEOs I see hold back-to-back interviews in which they ask the two candidates completely different questions. If you're basing the questions on the specific candidate's experience, it's unlikely you'll learn whether the person can perform the job you've outlined.
Like I said, interviewing is a science--which means to compare your findings, you have to keep at least one variable constant. By asking different candidates different questions, you're removing your ability to weigh them side by side.
2. Keep the questions related to the job they're applying for.
This is a big mistake I see a lot of hiring managers make.
If the question doesn't relate to the position, or the candidates' ability to do the job, then it shouldn't be asked. Period.
An interview is not the time to attempt to make a personal connection--the reason being that it tends to allow the candidate to control the interview, instead of the interviewer extracting the information he or she needs to make an educated and objective decision.
3. The questions you've prepared must include open-ended, closed-ended, and leading questions.
Every interview should involve these three types of questions. An open-ended question requires more than a yes or a no to answer, and is intended to give the candidate time to think and share a personal experience.
A closed-ended question can be answered with a simple yes or no.
And a leading question, you, the interviewer, ask to catch a glimpse into how the candidate thinks. For example, "I see you've managed a lot of projects in the past. Tell me why that's important to you and why you enjoy it." That's a leading question. So is a "what if" question. Again, you want to see how the candidate goes about thinking through and verbalizing his or her internal thoughts.
4. Don't ask opinion-based questions.
This should be common sense, but you'd be surprised how many hiring managers make this mistake.
Opinion-based questions get you nowhere in interviews. What you're looking to understand is a candidate's experience and, more important, his or her behavior. Opinion questions do not do a good job of predicting future behavior (which is essentially what you're banking on when you're hiring someone). Instead, keep your questions objective and aim to understand how the candidates operate, problem solve, and approach their work.
5. Just because they have the education and training, it doesn't mean they can do the job.
One of my favorite opening questions to ask a candidate is, "What do you know about our company?"
I ask because, if someone was interviewing to work at my company, LendingOne, it wouldn't take much effort for the person to know what we're up to in our industry. This simple question tells me out of the gate whether the candidate took the time to prepare, or if the person is on just another interview.
But let's say a candidate did his or her due diligence, and had studied enough to speak confidently about our company. Let's even say the person has a personal interest in our industry, and is already fairly educated on our offerings.
Unfortunately, that doesn't guarantee this person can do the job.
One of the hardest things you have to do, as an interviewer, is ask yourself whether the candidate in front of you is right for the role you're looking to fill. I find hiring managers are quick to hire someone they like, or someone they feel is knowledgeable about the space, without really asking themselves whether this individual is right for the role.
There's a big difference. And part of making great hires is knowing when a great candidate isn't the right fit.
