While completing a job application prior to an interview, it included the almost standard discrimination policy - company name redacted for my protection (you may need to click on the image to view it larger):

Race, ethnicity, religious affiliation, gender, disability, marital status & veteran status- all federally protected classifications. Sexual orientation - not federally protected but common in discrimination policies. However, this is the first time I've ever seen a company specifically protect people over the age of 40. Does this mean they will discriminate against people under the age of 40? With only 9.5 years until I hit this milestone, it's probably a good thing if I want to make a career there.
