These Companies Are Among the Hardest to Get Hired Into

Updated: Apr 26, 2016 9:16 PM UTC | Originally published: Mar 29, 2016

Some employees on Fortune's 100 Best Companies to Work For list just can't bear to part with their employers.

Perhaps its due to the benefits, the community, or the paycheck, but these 12 companies have an annual turnover rate at or below 4%, compared to a list-wide average of 10%. That means these companies have some very loyal employees who aren't willing to leave just yet.

The companies on this list range from insurance to cancer diagnostics and software firms, and have some workers who are willing to stay for the duration of their careers.

Scroll down to see some workplaces where it is difficult to get hired.

Nationwide Mutual Insurance

Voluntary turnover rate: 4%
Average number of applicants per opening: 17
The private national insurance company offers an hourly minimum wage of $15 and a hefty adoption assistance reimbursement of $6,000, making Nationwide favored by employees. With a staff of 34,000 people, about half of company's openings were filled internally over the past year, and 44% were filled by referral.
See why is Nationwide is No. 71 on Fortune's 100 Best Companies to Work For.

American Express

Voluntary turnover rate: 1%
Average number of applicants per opening: 53
American Express employs 20,620 U.S. employees, and gives "average difficulty" interviews to it's applicants according to a poll by Glass Door. The company also has about 734 jobs listings as of February, and filled a little over half of its positions internally.
When asked what kind of candidates they seek, the company wrote on Great Places to Work's website: "Candidates should be able to clearly articulate how their skills and experiences will help American Express move the business forward in the digital era. They should also demonstrate a track record for driving innovation and new ways of working that would help increase value to our shareholders and customers."
That said, the company is laying off about 20% of its workforce due to budget cuts.
See why American Express is No. 96 on Fortune's 100 Best Companies to Work For.

Acuity Insurance

Voluntary turnover rate: 2%
Average number of applicants per opening: 26
On average, Acuity Insurance employees stay with the firm for an average of ten and a half years, while 23.9% of employees who work at Acuity Insurance left the company in the last 12 months for retirement. That low turnover rate makes sense, because the company's core value is "have fun"— it even has popcorn machines and ping-pong tables to prove it. The company hired for 235 jobs in the 12 months ending in February, and filled 53 of those internally.

Hilcorp

Voluntary turnover rate: 3%
Average number of applicants per opening: 22
This Texas-based oil and gas producer had just eight job openings as of February 2016, and 8,572 applicants over the course of a year.
"The candidate on average will meet with four to five team members enabling us to get a variety of feedback regarding the candidate's ability. Many interviewees are often surprised to find our President on their interview schedule," the company reported according to Great Places to Work.

W. L. Gore and Associates

Voluntary turnover rate: 3%
Average number of applicants per opening: n/a
The synthetic fabric manufacturer's low turnover rate probably have something to do with its benefits, which include paid time off volunteer and a dedicated fun committees.  The company also has 446 associates who have stayed with the firm for over 30 years. Granted, the firm also added 654 new positions last year.
See why W. L. Gore and Associates is No. 12 on Fortune's 100 Best Companies to Work For.

Roche Diagnostics

Voluntary turnover rate: 4%
Average number of applicants per opening: 51
This cancer diagnostics company is likely well loved by its employees, with a fishing pond, gazebo, garden plots and numerous sporting facilities. Which may account for its 4% turnover rate.
Moreover, just under half of its jobs filled in the past 12 months were filled internally—which is most likely a reason for employees to stay with the company. 44% of jobs were filled via referral.
See why Roche Diagnostics is No. 73 on Fortune's 100 Best Companies to Work For.

Atlantic Health System

Voluntary turnover rate: 4%
Average number of applicants per opening: 45
Sixteen percent of full-time employees who left the company departed for retirement. And employees seem keen on staying for a long time at Atlantic Health Systems.
Whether its for the 95% healthcare coverage or fitness centers, about 20% of employees stay with the company for at least 10 years, while 10% stay for 20.
The company will also "always look internally first before something is posted externally" in regards to searching for a candidate.
See why Atlantic Health System is No. 79 on Fortune's 100 Best Companies to Work For.

SAS Institute

Voluntary turnover rate: 4%
Average number of applicants per opening: 33
Workers who work for SAS stay with the software company for an average of 12 years.
That perhaps has something to do with the fact that workers could practically live in the building, with swimming pools, medical clinics, car detailing, nail salons and more on-site.
The double digit years might also have something to do with the fact that most of the companies upper management come from within the company. About 85% of managers are from within, which is certainly a consideration motivating employee retention. The company also added 222 full-time jobs in 2015.
See why SAS Institute is No. 8 on Fortune's 100 Best Companies to Work For.

Genentech

Voluntary turnover rate: 4%
Average number of applicants per opening: 62
This 42-year-old biotech firm has kept a low turnover rate, but also added 1,684 employees in the past 12 months.
Genentech has about 13,704 employees now. Job hopefuls will have better luck getting jobs if they already work for the company or know someone there:Just under half of jobs are filled internally, while 38% are filled via referral.
"We believe it's our employees' shared mission to help people with serious diseases that truly enables us to attract the most talented people and keep them engaged in their work," a company representative noted.

Ultimate Software

Voluntary turnover rate: 4%
Average number of applicants per opening: 47
Given that the company pays 100% of the premium for employee healthcare and matches 401(k) plans at 40% with no cap, it's no surprise that the company keeps such a low turn over rate. 66% of those turnovers, 70 people, said they left for a new job. Another driver for retention: the company mainly promotes from within.
Meanwhile, employees are on average, 42 when they decide to leave the company, and an "unusually high percentage of our people stay throughout their careers," according to an Ultimate Software representative.
The company added 700 new positions last year, and noted that the position with the lowest turnover rate was Managers.
