They have constant ads for this position online, however, no matter how many times you try to apply and no matter if you are perfectly qualified they will not unless you know someone working there as a reference. I'm running into this issue with other companies as well. They ask if you have a friend or family member working there on the application. If you leave it blank or say, "no," you are not given a chance. This is precisely how nepotism and other negative factors arise within a company's culture.
