Five Biggest Mis-Hiring Mistakes

By Dana Borowka, MA

Ready. Aim. Mis-hire.

Unfortunately, that is a common problem for many companies. That mis-hire can have a big negative impact on your company’s bottom line. Worse, it could hurt work force morale.

Each mis-hire decision can cost your company well over two to three times the individual’s salary, according to author Barry Deutsch of Impact Hiring Solutions. This figure may be a conservative estimate because of factors like training, evaluation, termination, re-initiating the hiring process, and lost opportunity costs.

There is also an emotional factor involved in a mis-hire. Not only can it cause stress and anxiety for both management and employees, but it also takes away focus from your company’s primary goals.

According to research by Deutsch, co-author of the best-selling book You’re Not The Person I Hired, here are the five biggest mis-hiring mistakes to avoid:

Mis-Hiring Mistake #1. Not taking the time to define success. Not defining success up front is almost a guarantee of a mis-hire. Defining success is the number one issue behind problems with hiring, performance management, and engagement. Defining success up front dictates where you go to find the candidate, it provides 80 percent of your interview questions, and it lays out performance expectations that you can use in interviewing.

Mis-Hiring Mistake #2. No formal hiring process. If there is one key to overcoming most of the mis-hiring mistakes that managers make, it is by developing a rigorous and disciplined hiring process. This kind of process has two major components: a detailed step-by-step process, and written forms and questions prepared in advance. Although each hiring experience may have its unique aspects, most follow a consistent process. Best-practice information on hiring found in many books and websites can form the basis of your step-by-step process. But once you settle on a process after trial-and-error, it needs to be written down in the form of a checklist or procedure so that each hire follows a complete course of action.

Mis-Hiring Mistake #3. Not shaking the bushes hard enough to uncover the best candidates. Most companies post generic job descriptions on generic job boards and pray the best person drops into their lap. Sometimes, you might do a little superficial networking. The tactic of posting the job usually brings the bottom third of the candidate pool to your doorstep – all the worse candidates. Sometimes you get lucky. There is an old adage that goes: “Even a blind squirrel can find a nut sometimes.” It’s tough to build high performing teams based on luck and hope. Running generic ads on generic job boards shows up a small microcosm of the candidate pool – those who are unemployed, or desperate to leave their current organization. If you want to fill your funnel with outstanding talent, you have to work at compelling the best to come forward by writing compelling marketing statements to replace the disgusting use of job descriptions, networking, referrals, and direct sourcing using tools like LinkedIn.

Mis-Hiring Mistake #4. Ignoring character and values. Have you heard the expression, “People are usually hired for experience and fired for character.” With today’s emphasis on resume screening and superficial interviews, about the only information a hiring supervisor can glean from a candidate are the facts of past experience and skills. Talent, skills and experience are important, but after the hiring is done, real people show up with their own values, morals, and motivations.

Mis-Hiring Mistake #5. Failing to use in-depth work style and personality assessment. You must have an interview process designed to validate, verify, and vet whether the candidate can achieve your desired results, and whether they will be a good fit for your culture and values. That includes assessments. As with any business decision, having the right information is critical. Work style and personality assessment testing can provide insight into potential hires, as well as your current workforce, in three main ways:

1. Identify potential red flags. A personality assessment can discover issues that are sometimes overlooked during the interviewing process and can quantify an intuition or feeling the interviewer may have about a particular candidate. It can be used to identify potential red flags concerning behavioral issues, help understand how to manage individuals for greater work performance and compare interpersonal dynamics of teams, departments and candidates.

2. Learn how to optimize employees’ work performance. A personality assessment can provide extensive information on an individual’s ability to work with their job responsibilities, team dynamics and company culture. Additionally, the assessment can show effective strategies to gain optimal performance from that individual within their particular work environment. It can also be employed to quickly identify the most effective management style for a new employee or predict how team members are likely to interact.

3. Ensure you have the right people in the right positions: Additionally, personality assessments can be utilized in rehires, or situations which call for employees to re-apply for their current jobs, as in the case of a corporate merger or restructuring. A personality assessment can also ensure that your company continues to have the right people in the right positions and distribute assets and talents effectively.

Legal Guidelines For Assessing Recruits

A frequent question from companies and organizations concerns the legal guidelines in administering assessments to potential employees. Industry regulations can vary and the best option is to consult with your company’s trade association along with reading through the EEOC guidelines by visiting Additional information can be found online at the EEOC website, in the Disability-Related Inquiries and Medical Examinations of Employees section: The EEOC is the end all of end-alls. So, no matter what people say, always go by what the EEOC has outlined.

As a general rule if your company uses an assessment, any test or set of hiring questions must be administered to all of the final candidates in order to assure that discrimination is not present.

The Bottom Line

An in-depth work style and personality assessment is only one component needed for a successful recruitment and hiring program. It can provide valuable information for critical personnel decisions. Combined with an effective recruitment program and skilled interview techniques, it can benefit your company as a whole, in addition to your individual employees. Armed with accurate and quantifiable data from an in-depth personality assessment, the interview process becomes much more reliable. Ultimately, this only adds to your organization’s bottom line, allowing more effective management of your existing workforce and limiting the potential for wrong hiring decisions.
