Non existent. If you are over 30 don't waste your time. Rude HR representatives. Very arrogant and entitled staff. Age phobic. It is a shame that the company does not value experience in fortune 500 companies, preferring a culture of youth and inexperience. Several years ago I scheduled a phone screen that I had to reschedule due to a work commitment. The HR representative refused my phone calls and contact. This company does not walk the talk.
