So you're looking for a job after finally getting that degree. You look at the top companies in the United States but you're unsure which company to go for.

But some companies are not easy to penetrate. Maybe it's because of the benefits, the work environment, the community, or those extra zeroes in the pay check. But when you see a company that has a turn over rate of 4% or below (compared to the others that have 10% or higher), then these companies must be doing something right to increase, sustain or manage their employee retention.

Fortunately, Fortune has come up with a list of companies that are among the hardest to get hired into.

1. Nationwide Mutual Insurance (Voluntary turnover rate: 4%) - $15/hour minimum wage with a hefty adoption assistance reimbursement of $6,000.

2. American Express (Voluntary turnover rate: 1%) - 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."

3. Acuity Insurance (Voluntary turnover rate: 2%) - The company's core value is "have fun"- it even has popcorn machines and ping-pong tables to prove it.

4. Hilcorp (Voluntary turnover rate: 3%) - "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.

5. W. L. Gore and Associates (Voluntary turnover rate: 3%) - It has something to do with its benefits, which include paid time off volunteer and a dedicated fun committees.

8. SAS Institute (Voluntary turnover rate: 4%) - Workers can practically live in the building. With swimming pools, medical clinics, car detailing, nail salons and maybe that double digit salary.

9. Genentech (Voluntary turnover rate: 4%) - 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," says the company rep.
